Effect of Magnetic Flow and Convective Heat Transfer Enhancement Using Hybrid Nanofluid: A Structured Review

Convective heat transfer is vital in a variety of engineering applications, including thermal management systems, electronic refrigeration, and energy conversion devices. Improving the rate of heat transfer in these systems is of the utmost significance for increasing their efficiency. This review focuses on the single and combined effects of these parameters on improving heat transmission in such systems. The heat and mass transfer of nanofluid is greatly influenced by various factors, including the intrinsic features of the nanofluid, the process used for synthesising the nanofluid, the impact of magnetic force, the concentration and size of nanoparticles, and the Reynolds number (Re). Furthermore, it is important to note that the material characteristics, thermal properties, and performance of magnetic nanofluids are significantly influenced by slight variations in the magnetic force and magnetic field gradient. Multiple research projects have reached the agreement that the inclusion of a magnetic field within magnetic nanoparticles enhances the convective heat transfer capabilities of a nanofluid, resulting in an improvement ranging from around 13% to 75%. Moreover, several applications of hybrid nanofluids in thermal systems have been introduced.

Study of dielectric-based thermal management of second-life battery packs with rectangular vortex generators

The performance of lithium-ion battery (LiB) is influenced by the operational temperature. The thermal management of the battery module depends upon the interaction between coolant and battery surface. The study focuses on analysis of vortex interactions as a commercial dielectric coolant (FC 3283) circulates within battery module. The analysis indicates that the arrangement reduces the maximum average temperature by 26 °C in comparison with the conventional methods. However, a maximum temperature difference of 4 °C persists at final row of battery cells. Therefore, the vortex generators (V.G.) are deployed to alter the flow behavior to achieve uniform cooling of LiB. Rectangular V.G. alleviates the temperature difference by stretching primary vortices. The V.G.s promote smaller induced vortices, enabling a multiscale distribution of turbulent kinetic energy, reducing the concentration of turbulence near central region of the cell. The induced vortices ensure uniform heat transfer along the cell length. Furthermore, a 15% increase in vorticity magnitude and a 33% rise in an average Nusselt number in the region near the last-row cells is achieved. Overall, employment of V.G.s results in a 2.5 °C reduction in maximum cell temperature difference. A novel metric, the operational effectiveness factor (OEF), is coined to assess the combined effect of heat transfer enhancement and additional pumping requirements resulting from the different positions of the V.G. A high OEF value implies the ability of the configuration to maintain a more uniform cell temperature while ensuring lower parasitic power. Middle V.G. configuration achieved highest OEF of 1.35, while bottom V.G. configuration exhibited lowest OEF of 1.11.

Heat transfer enhancement and long-term test of non-ionic Triton surfactant with different hydrophilic chain lengths

Surfactant aids boiling enhancement, but the related mechanism is not yet comprehensively understood. For mechanism investigation on surfactant molecule, most of existing studies focused on its hydrophobic part, while research on hydrophilic part is scarce. In this paper, a group of non-ionic Triton surfactants with same functional group but different hydrophilic chain lengths were experimentally tested for pool boiling on flat copper. At critical micelle concentration (CMC), long-chain Tx-405 exhibited higher heat transfer coefficient (97.4 kW/(m2·K)) than Tx-100 (77.1 kW/(m2·K)) and Tx-114 (77.4 kW/(m2·K)). Long-term test indicated a gradually deteriorating trend of heat transfer performance from days on. Solution properties and bubble dynamics were measured. At low concentration, surfactant with shorter hydrophilic chain has better heat transfer performance due to greater surface tension reduction. The increase of hydrophilic chain length improves water affinity of surfactant and thus leads to higher CMC. If there is no restriction for surfactant concentration, a longer hydrophilic chain is favorable for higher heat transfer coefficient at CMC. The results in this paper provide insights for mechanism investigation on surfactant, promote further design of new surfactant, and contribute to the prediction of heat transfer enhancement effect.

Swirl development and enhanced heat transfer analysis of ferrofluid in elliptical ducts under thermal-magnetic-flow fields coupling

It is a new practical method to apply external magnetic field in magnetic working fluid to enhance heat transfer. In this paper, the swirl flow and heat transfer characteristics of ferrofluid in elliptical tubes under thermal-magnetic-flow fields coupling have been studied by using the finite volume method. The flow structure and secondary vortices evolution process of magnetic nanofluid in elliptical ducts under the action of the magnetic fields have been obtained. The effects of magnetic induction intensity and the ratio of major axis to minor axis of elliptical pipe on the flow and heat transfer performances have been main investigated. The results show that there is obvious secondary flow (with four vortices or eight vortices) on the cross section and the swirling flow is gradually formed due to the coupling of thermal-magnetic-velocity fields. With the increase of the ratio of major axis to minor axis, the heat transfer enhancement effect with the application of external magnetic field is weakened. The comprehensive performance of flow and heat transfer are better at lower Reynolds number and higher magnetic induction intensity.

Hydrate deposition characteristics analysis and structural optimization design of reduced-diameter pipe based on an improved model

High-pressure and low-temperature conditions in deep-water development are probably going to cause serious hydrate deposition problems. Current studies on hydrate migration and deposition are mainly centered on through-diameter conditions, and relatively few studies have been carried out for reduced-diameter conditions. Meanwhile, the effect of heat transfer between the particle-fluid-wall in the pipe on hydrate particle deposition is usually neglected, resulting in discrepancies between results and reality. Here, an improved hydrate deposition-stripping model is developed based on hydrate particle adhesion and rebound as well as deposition and stripping criteria, and combined with the inter-phase heat transfer characteristics. The effects of several important parameters, such as thermophoretic force and pipeline structure, on the deposition characteristics of micron-sized hydrate particles were investigated, and the deposition mechanism of hydrate in special pipelines was revealed. Also, the combination of calculation results provides new ideas for the design of oil and gas pipes. Based on the enhanced mechanism of hydrate particle deposition in the reduced-diameter pipe proposed in this paper, a new parameter of hydrate particle deposition enhancement rate (ξh) is defined to characterize the integrated enhancement effect of reduction structure and heat transfer in the pipe on hydrate particle deposition, and a new correlation calculation method is provided for it. The results can provide a valuable reference for efficient and accurate calculation of hydrates.

Flow and heat transfer characteristics of microencapsulated phase change material slurry in bonded triangular tubes for thermal energy storage systems

Three nanoscale metal oxides composed of nano TiO2, nano Al2O3, and nano MgO were added to the phase change microcapsule slurry for optimising the heat transfer behaviour. The thermal and rheological properties of the resulting microencapsulated phase change materials (MPCMs) and microencapsulated phase change material slurries (MPCSs) were characterized to determine the effects of added metal oxides in optimising the performance of MPCSs. The impacts of factors like metal oxides, concentrations, and flow rates on the heat transfer behaviour of MPCSs were investigated by forced convective heat transfer experiment with various working conditions. Compared to 6 wt% MPCSs, the heat transfer coefficients (hx) of 6 wt% slurries containing 1 wt% TiO2, 1 wt% Al2O3, and 1 wt% MgO increased by 4.0 %, 2.5 %, and 7.13 %, respectively. Nano-MgO showed the most significant heat transfer enhancement effect on MPCSs. Moreover, the heat transfer performance gradually enhanced as a function of the concentration for nano MgO. Overall, the addition of metal oxides enhanced heat transfer by increasing the thermal conductivity of the slurry, as well as improved the micro-convection effect. The proposed MPCSs are promising for applications in solar photovoltaic/thermal (PV/T) systems, chip cooling, thermal management, buildings, and automotive cooling.

Study on the heat transfer enhancement characteristics by flow-induced vibration of inserting polyethylene membrane inside the channel

With the development of science and technology, the heat dissipation problem of high-density electronic products has gradually emerged in engineering practice. In this paper, the enhanced heat dissipation process of fluid induced oscillation through flexible membrane is proposed, which belongs to the multi-field synergistic bidirectional coupling effect of thermal-fluid-solid coupling. Through the comparative numerical analysis of the flow induced oscillation of the flexible membrane and the fixed rigid fin in the flow channel, the mechanism of the fluid induced oscillation of the flexible polyethylene membrane is revealed. Based on the two-way fluid-solid coupling method, a numerical model for the heat transfer process of polyethylene membrane with thickness of 0.02 mm in the fluid channel was established. The temperature field, Nu (Nusselt number) and PEC (Performance comparison index) number of the rigid fin and polyethylene membrane installed in the channel under different Reynolds numbers were calculated respectively. The ratio of the length of the membrane to the height of the channel was adjusted for multiple groups of calculations to verify the positive effect of the polyethylene membrane installed in the channel on the heat exchange effect. The results show that in the fully developed area of heat transfer, the channel with polyethylene membrane is better than that with rigid fins in terms of turbulence and vortex shedding; at Re = 4400, the comprehensive enhanced heat transfer factor of heat exchange is the largest, up to 1.27; as the ratio of the height of the new flexible membrane to the height of the channel is 1, the heat transfer enhancement effect is best. In the next step, the correlation theory between oscillation characterization parameters and heat transfer enhancement effect under pulsating fluid excitation will be investigated.

The effect of dimple/protrusion arrangements on the comprehensive thermal performance of variable cross-section rotating channels for gas turbine blades

The cooling structure design of turbine blades plays a vital role in ensuring the safety and reliability of the entire gas turbine set. Our team's previous research revealed the influence of the rotating and variable cross-section effect on the aerothermal characteristics of the channel. In order to further enhance the cooling performance, four types of dimple/protrusion arrangement schemes are applied to five channels with different height ratios in this research. The detailed flow-heat transfer-friction characteristics and comprehensive thermal performance of each channel are obtained. The results show that the introduction of heat transfer enhancement element produces obvious heat transfer enhancement effect. Compared with the smooth reduced cross-section channel, the Nu/Nu0 is increased by 10.9 % (height ratio = 4:1, both of two passes are arranged by protrusions). For the rough expand cross-section channel, the Nu/Nu0 is increased by 8.9 % (height ratio = 1:2, the first pass is arranged by protrusions and the second pass is arranged by dimples). Within the scope of this paper, the arrangement scheme of both of two passes are arranged by dimples has the best comprehensive thermal performance. The arrangement scheme of both of two passes are arranged by protrusions has the highest Nu/Nu0, but also the highest f/f0.

Barrier effect, blocking effect, and interference effect of electrohydrodynamic heat transfer enhancement in rectangular channels

This study investigates the heat transfer enhancement by electrohydrodynamic (EHD) in a rectangular channel with various geometric and operational parameters in a wide NEHD range of 0.4–5. Here, NEHD is a dimensionless number, describing the ratio of electrostatic, inertial, and viscous forces. Two working regimes in EHD are identified: inertial and electrostatic regimes. The results show that the barrier effect exists only in the inertial regime; however, the interference effect occurs in the electrostatic regime. The barrier effect relies heavily on NEHD rather than the dimensionless distance between electrodes l* and the dimensionless channel width H* because the thermal boundary layer cannot be disturbed sufficiently by a small electrostatic force; however, the interference effect depends on l* and H* rather than NEHD due to the stagnant area initiated only by a strong interaction between adjacent emitting electrodes. A new effect, the “blocking effect,” is found in the electrostatic regime. The mechanism of the blocking effect is different from that of the barrier and interference effects. The blocking effect is initiated by a giant vortex, which “blocks” the airflow flowing toward the downstream channel. The average Nusselt number of channels can be reduced by at least 8%, 13%, and 5% for the barrier, interference, and blocking effects, respectively. A working spectrum of EHD-induced heat transfer enhancement in a rectangular channel is provided under NEHD and channel area coupling conditions. We believe the spectrum can help in designing EHD-induced heat transfer enhancement because it provides theoretical guidance for avoiding the three effects.

Numerical investigations on the effect of bubble injection on heat transfer of natural convection in laminar flows

AbstractIt was found that the injection of bubbles into liquid can effectively improve heat transfer efficiency, so it is important for industrial applications to investigate the effect of bubble injection on heat transfer. The effect of bubble injection on natural convective heat transfer in steady laminar flows in a vertical channel is investigated using the volume of fluid (VOF) method, and the effects of bubble diameter, Eötvös number (Eo), bubble arrangement, and bubble distance from a hot wall on the heat transfer between the hot wall and liquid are studied, respectively. The results show that bubble injection can effectively improve the heat transfer between the hot wall and liquid; an increase in bubble diameter and Eo can improve the enhancement effect of heat transfer and can expand the enhancement area of heat transfer; the closer to the hot wall a bubble is, the better the enhancement of heat transfer is; and the spacing and arrangement of bubbles also have important effects on the heat transfer between the hot wall and liquid. The comparison shows that the enhancement of heat transfer is the best for the vertical arrangement of double bubbles, which increases the local heat transfer coefficient by 3.2 times. The enhancement of heat transfer generated by bubble injection is related to the degree of disturbance of the local liquid phase caused by bubble injection. The more strongly the local liquid is disturbed, the thinner the local temperature boundary layer becomes, and the better the enhancement of heat transfer is.

Improving the performance of room temperature magnetic regenerators using Al2O3-water nanofluid

The present study examines the use of Al2O3-water nanofluid as the heat transfer fluid in a magnetic regenerator and evaluates the improved cooling capabilities of the device. Room-temperature magnetic refrigeration exploits a special property of some materials, the “magnetocaloric effect”, that is the ability of the material to change its temperature when exposed to rapid changes in an external magnetic field. As adiabatic magnetic field variations of 1 to 1.5 T produce a small temperature change of a few degrees, active magnetic regeneration is often employed to achieve larger temperature spans for practical cooling applications. The effectiveness of this process greatly depends on the properties of the heat transfer fluid, which is usually a water-based mixture. High values of the fluid thermal conductivity enhance heat transfer allowing for higher cooling capacity. This work presents the outcome of a comprehensive simulation study evaluating the improved performance of a gadolinium-based regenerator using a water-based mixture with added Al2O3 nanoparticles as the heat transfer fluid. In this analysis, both the volume concentration of nanofluid and the particle size were varied. The combined effect of heat transfer enhancement and pressure drop increase was also investigated through the second law efficiency. On average, a more than 15 % increase in cooling capacity was observed when using Al2O3 (6 % vol, 20 nm particles), and the COP can be preserved or increased with a properly tuned regulation of the cycle time and the utilization factor of the regenerator.

Mini-channel cooling system for solar PV Panels with hybrid magnetic nanofluid and magnetic field

This study delves into the interplay between magnetic fields, heat transfer, and fluid behavior within a 3D mini-channel. Exploring the effects of a magnetic field on a hybrid nanofluid (Fe3O4–TiO2) under varying intensities (1000–2000 Gauss) and positions. Using numerical simulations (finite volume method), key parameters like Nusselt number (Nu), Friction factor (f), and Thermal Enhancement Factor (TEF) have been analyzed to uncover how magnetic fields and nanofluids interact in complex geometries. Results showed that the application of a magnetic field significantly enhanced heat transfer performance, with a maximum Nusselt number enhancement of 230%. Moreover, it was shown that greater magnetic field intensities were associated with elevated friction factors, whereas friction factors exhibited a declining trend as Reynolds numbers increased. The thermal enhancement factor initially increased with Reynolds numbers, but declined after reaching a peak. However, higher magnetic field strengths mitigated this decline, intensifying heat transfer enhancement effects reaching a maximum of 2.18 at 2000G magnetic field. These findings provide quantitative insights into the effectiveness of magnetic fields in enhancing heat transfer in Fe3O4–TiO2 hybrid nanofluids.

Secondary vortex drag reduction and heat transfer enhancement of nanofluids in hierarchical microchannels applied to thermal management of electronic components

In order to improve the heat dissipation performance of electronic components, two hierarchical microchannel structures with curve and straight corners are proposed, and semi-circular and trapezoidal secondary flow structures are introduced into the structure with the best performance. The effects of coolant (Fe3O4-water nanofluid), layered structure and secondary flow structure on the comprehensive performance of MCHS were studied by numerical simulation. Results showed that deionized water is more suitable for the heat dissipation of microchannels at this scale. The hierarchical structure has the effect of enhancing heat transfer, and Nu can be increased by up to 67.32 %. The introduction of secondary flow structure has drag reduction effect in a certain Reynolds number range. The hierarchical MCHS with semi-circular secondary flow structure has drag reduction effect in the Reynolds number range of Re = 200–400, and the pressure drop can be reduced by up to 1.89 %. The hierarchical MCHS with trapezoidal secondary flow structure always has a drag reduction effect in the range of Reynolds number Re = 200–600, and the maximum pressure drop can be reduced by 2.46 %, showing excellent drag reduction ability. In addition, the introduction of trapezoidal secondary flow in MCHS increases the Nusselt number by 9.70 %, the comprehensive performance index reaches 1.10, and the cooling performance and comprehensive performance are optimal. The combination of hierarchical structure and secondary flow structure has excellent drag reduction and heat transfer enhancement effects, and has broad application prospects in the field of thermal management of electronic devices.

The heat transfer enhancement of the converging-diverging tube in the latent heat thermal energy storage unit: Melting performance and evaluation

Latent heat thermal energy storage (LHTES) has emerged as a promising approach to settle the intermittent and fluctuant of renewable energy but heat transfer enhancement is necessary due to the low thermal conductivity of the phase change material (PCM). This study numerically investigated the heat transfer enhancement effect of the typically converging-diverging tubes (CDTs) inside a shell-and-tube LHTES unit. The evolution of melting behavior was analyzed to describe the heat transfer enhancement mechanism of the CDT. Based on the enhancement effect and pump power consumption associated with the CDT, a modified performance evaluation criterion (PEC) was established to evaluate the feasibility of current designs. The arrangement of CDTs was found to significantly improve the heat transfer performance of LHTES. The triangle CDT exhibited the maximum melting time reduction of 20.77%. The heat transfer enhancement effect of CDT was attributed to the enhanced natural convection of PCM and forced convection of heat transfer fluid. The analysis of the evaluation ensures the feasibility of the new criterion and its specific application field. Moreover, it was worth to note that the triangle CDT achieved the best cost performance of 0.363 ω, where ω represented the return factor.

Numerical simulation and structural optimization of spiral finned tube thermal energy storage

Thermal energy storage (TES) has emerged as a promising solution to enhance nuclear safety by passively removing decay heat during reactor shutdown and accidents, thus preventing overheating of the reactor core and protecting the integrity of containment barriers. The research of TES with different structures has broad application prospects and practical significance. In this study, the melting process of phase change material (PCM) in various TES structures was simulated by the numerical simulation method in two and three dimensions. The mechanism of gravity-driven natural convection enhancing heat transfer was revealed. The effects of different TES structures, fin pitch, fin height, and fin thickness on heat transfer performance were studied. The results showed that many vortices formed by liquid PCM are the main reason for enhancing the natural convection. Adding fins could greatly accelerate the heat storage process. The melting time of PCM in annular and spiral finned tube TES was 47.3% and 61.3% less than that in smooth tube TES, respectively. In the present study, the heat transfer effect was enhanced as the spiral fin pitch became small, the fin height increased and the fin thickness increased. Two opposite effects of fin structure on the natural convection were revealed: (1) positive effect provided by heat transfer enhancement and (2) negative effect produced by blockage.

A novel design for fin profile in metal hydride reactor towards heat transfer enhancement: Theoretical derivations and analysis

Hydrogen storage using metal hydrides is one of the research hotspots in the field of energy storage. However, metal hydride powders are known to have low thermal conductivity, which causes significant temperature fluctuation and hinders further reaction, hence efficient thermal management is a must for hydrogen storage using metal hydrides. In this paper, based on the principle of entransy dissipation, the optimal profile of fin in a cylindrical reactor under steady-state conditions is deduced. The expression for the temperature distribution of the bed is also obtained, which could clearly account for the influences of multiple involving factors, such as fin thickness, fin spacing, and radius of reactor. Through simulation, the characteristic time of hydrogen absorption for reactor inserting the optimized fin, is shortened by 19.1 % compared with the conventional uniform thickness fin. The influence of the geometric parameters of storage reactor was further discussed. When the ratio of the inner and outer radius of the reactor is confined (rr/rt≤2), linear thinning fin can be seen as a reasonable simplification of the optimized fin with comparable heat transfer enhancement effect. This study proves that the thermal management of metal hydride reactors, particularly those inserting high thermal conductivity materials like graphite, can be optimized quantitatively by entransy theory.

Research on the audible acoustic field-enhanced heat transfer of double-pipe exchangers: Effect of laminar flow and turbulence, vertical and horizontal placement of pipes

The acoustic field is considered an efficient and reliable technique for enhancing convective heat transfer. This study investigates the optimal experimental conditions of acoustic field-enhanced heat transfer using an experimental platform for convective heat transfer in a double-pipe exchanger. The experiment mainly explored the enhancement effect of the acoustic field on heat transfer by comparing laminar flow and turbulent flow states, as well as the arrangement of horizontal and vertical pipes. Meanwhile, acoustic wave frequency and inlet temperature of the thermal fluid were also considered as experimental variables. The results showed that compared to the horizontal pipe which has the best reinforcement efficiency at a frequency of 0.6 kHz, the vertical pipe in the laminar flow condition showed a high heat transfer capacity in the range of 0.6–0.8 kHz, with the best reinforcement efficiency reaching up to 43.6%. The significant heat transfer enhancement effect is mainly because 0.6 kHz is close to the acoustic resonance frequency, which further enhances the heat transfer effect. In the turbulent flow condition, the effect of the acoustic field on enhancing heat transfer is obvious when the pipe is arranged horizontally, and the reinforcement efficiency reaches a maximum of 24.5% at a frequency of 0.7 kHz.

Heat transfer characteristics of tubular heat exchanger using reverse air injection flameless combustion

The heat transfer characteristics of a co-axial triple tube reformer using flameless combustion were studied herein. Methane steam reformers for hydrogen production have been developed with a long history, but as hydrogen has recently come into the limelight as a future energy, research on the development of more efficient reformers is being pursued. Flameless combustion has the advantage of being applicable for the high performance reformers, but studies to date have focused on the combustion phenomenon itself, and research on the heat transfer phenomenon is lacking. In this study, RAI (reverse air injection) flameless combustion, which generates high intensity combustion and heat transfer, was applied to the reformer and its heat transfer effect was analyzed in parallel with experiments and CFD analysis. In the experiment, it was confirmed that the RAI flameless combustion increased the heat transfer by up to 58% compared to the conventional flame type combustion, and the case of two air nozzles was found to have a better heat transfer enhancement effect than the case of four. However, the case using four air nozzles showed a more axisymmetric flow pattern. The heat transfer enhancement effect of RAI flameless combustion is caused by the high-speed air jet creating a highly recirculating flue gas to generate uniform temperature distribution and high convective heat transfer on the surface. As RAI flameless combustion is characterized by being mixed with fuel at the rear end of a strong air jet, which is a completely different configuration from these existing combustors, it is expected that the limitations of the EDC model, which has been widely used in previous studies, will become more prominent. The equilibrium-PDF model based on chemical equilibrium and tabulated chemistry gave a closer result to the experimental results.

Effects of different working gases on the heat transfer enhancement performance of a heating tube with spiral insert under oscillatory flow

The working gas type had an important effect on the heat transfer performance of the turbulence device in the heater of Stirling engine, but the related researches were scarce, especially under the oscillatory flow. This work investigated the effects of four working gases (i.e., H2, He, N2, and CO2) on the heat transfer characteristics of a heating tube with spiral insert compared with a smooth tube under oscillating flow for a Stirling engine. The transient physical fields under different phase angles in an oscillatory cycle were analyzed, and the Nusselt (Nu) number, pressure loss and outlet temperature of working gas were studied. The results show that the cycle average Nu number of the enhanced tube with H2, He, N2, and CO2 as working gas increased to 1.67, 1.62, 1.61 and 1.72 times when comparing with those of the smooth tube. The cycle average friction coefficient increased to 1.96, 2.37, 2.36 and 2.62 times, respectively. Moreover, the performance evaluation criterion (PEC) values of the enhanced tube using the four types of working gas were all greater than 1 (1.21∼1.33). This implies that the comprehensive heat transfer performance of the heating tube with spiral insert was all improved with the four types of working gas. Moreover, the heat transfer enhancement effect was best when hydrogen was used. While considering the thermodynamic performance and safety reliability, the helium was more recommended. The findings are beneficial to enhance the operating efficiency of a Stirling engine.

Study of the effect of regenerative heat transfer enhancement on the silicothermic reduction process

As the main process for industrialized production of crude magnesium, the silicothermic reduction technology has problems such as high energy consumption per ton of magnesium and serious pollution. Under the policy of carbon peak and carbon neutrality, the implementation of energy conservation and pollution reduction technology reform has become an urgent issue in the silicothermic reduction process. Although the thermal conductivity of the briquettes used for magnesium production is low, they will absorb a lot of heat during the reduction reaction. As a result, the heat cannot be transferred quickly enough for the chemical reaction endothermic, leading to a slow magnesium production reaction and low production efficiency. Therefore, in-depth study on the kinetic mechanism of the improved heat transfer coupled chemical reaction is required to decrease the production cycle and increase efficiency. In this work, the effect of filling the voids of briquettes with regenerative particles of different materials on heat transfer process was first studied by means of experiments. It has been discovered that as the thermal conductivity of the filling material increases, the heat transfer process is accelerated, but the endothermic behavior of the regenerative particles at room temperature during the heating process seriously affects the heat transfer to the briquettes. On this basis, the models of heat transfer and magnesium reduction kinetics were combined and the recycling technology of high temperature regenerative particles with different materials was studied by numerical calculation method. The findings demonstrate that the production cycles for filling aluminum oxide, silicon carbide and silicon nitride are reduced to 6, 4 and 1 h, respectively, at the initial temperature of 1373 K for the regenerative particles, compared with the 8 h of the traditional method. However, when the voids of the briquettes are filled with quartz sand with a thermal conductivity close to that of the briquettes, the period increases to more than 10 h. When the initial temperature of the filled regenerative particles decreases, the production cycle also increases. In industrial production, materials with high thermal conductivity should be selected as regenerative particles as far as possible on the basis of considering the cost, and thermal insulation measures should be taken to minimize the heat loss during the recycling of regenerative particles.
