Engineering Interfacial Effects in Electron and Phonon Transport of Sb2Te3/MoS2 Multilayer for Thermoelectric ZT Above 2.0

AbstractEfficient thermoelectric (TE) conversion of waste heat to usable energy is a holy grail promising to address major societal issues related to energy crisis and global heat management. For these to be economical, synthesis of a solid‐state material with a high figure‐of‐merit (ZT) values is the key, with characterization methods quantifying TE and heat transport properties being indispensable for guiding the development of such materials. In the present study, a large enhancement of the TE power factor in Sb2Te3/MoS2 multilayer structures is reported. A new approach is used to simultaneously experimentally determine the values of in‐plane (kxy) and out‐of‐pane (kz) thermal conductivities for multilayer samples with characteristic layer thickness of few nanometres, essential for the quantification of the ZT, the key parameter for the TE material. Combining simultaneous enhancement in the value of in‐plane power factor (to (4.9 ± 0.4) × mWm−1 K−2) and reduction of the in‐plane value of the thermal conductivity (to 0.7 ± 0.1 Wm−1 K−1) for Sb2Te3/MoS2 multilayer sample led to high values of ZT of 2.08 ± 0.37 at room temperature. The present study, therefore, sets the foundation for a new methodology of exploiting the properties of 2D/3D interfaces for the development of novel fully viable thermoelectric materials.

Entropy analysis in thermally stratified Powell-Eyring magnesium-blood nanofluid convection past a stretching surface

Recently, researchers are very possessive to examine the treatment of diseases caused due to the deficiency of magnesium. The deficiency of magnesium in blood caused Hypomagnesaemia, which is further stimulus for various diseases such as vomiting, sleepiness, nausea, loss of appetite etc. In order to cover such deficiency, magnesium is injected in blood (base fluid) as a nanoparticle. Based on the above applications, the current research focuses to cover the deficiency of magnesium through Powell-Eyring (Magnesium-Blood) nanofluid flow deformed by the linearly stretchable sheet in the vicinity of stagnation point. Linear thermal stratification, viscous dissipation and Joule heating are incorporated to disclose the heat transport properties. Magnetic field is implemented to the nanofluid with an angle α. A system of dimensionless governing equations is achieved through appropriate transformations. Physical behaviors of temperature and velocity fields are elaborated through comparative graphs. Skin friction, entropy generation, rates of heat transfer and Bejan number is disclosed through graphs corresponding to pertinent parameters. The well-known convergence method (Homotopy analysis method) is utilized to achieve the solution of the model. Decrement occurs in temperature field for dominant melting and thermal stratification phenomenon. Entropy has same scenario in case of dominant melting while inverse behavior in term of thermal stratification. Bejan number is de-escalates with the escalation of Eckert number. Also, it is worth mentioning that the velocity outline accelerated and temperature profile decelerated with the enhancement of melting parameter. It shows that recovery rate of magnesium patients may be enhanced through medicine with enriched magnesium nanoparticles depending on the health of the patient.

Convective Performance of C5-Flouroketone-Based (C5-FK) and C4-Flouronitrile-Based (C4-FN) Gas Mixtures and SF6

Abstract SF6 is a widely used insulating gas in the electric power industry due to its high dielectric strength. However, SF6 is classified as a greenhouse gas and has a very high global warming potential (GWP). Much research and development efforts have focused on finding alternatives to SF6 which have a lower GWP. An important requirement for an SF6 alternative is that it has similar heat transport properties to SF6, since one aspect of the design of high voltage equipment is the management of the heat dissipated from the flow of current. In the present paper, we compare the convective performances of SF6 and C5-flouroketone (C5-FK) and C4-flouronitrile (C4-FN) based gas mixtures. Mixtures of CO2, O2, and C5-FK/C4-FN have a GWP much smaller than that of SF6, a high dielectric strength, are not classified as toxic, and have good arc interruption properties. The numerical study is based on a semi-coupled computational electromagnetics (CEM) and computational fluid dynamics (CFD) analyses. The results of the numerical study are compared with experiments. There is a good agreement between the simulation results and the experiments. C5-FK and C4-FN based gas mixtures have good convective performance and are well-suited for application in circuit breakers. Thus, from the temperature-rise point of view, C5-FK and C4-FN based gas mixtures represent an alternative to the SF6 insulating gas traditionally used.

Analysis of Heat Transfer of Mono and Hybrid Nanofluid Flow between Two Parallel Plates in a Darcy Porous Medium with Thermal Radiation and Heat Generation/Absorption

In the last two decades, academicians have concentrated on the nanofluid squeezing flow between parallel plates. The increasing energy demands and their applications have seen the focus shifted to the hybrid nanofluid flows, but so much is still left to be investigated. This analysis is executed to explore the symmetry of the MHD squeezing nanofluid (MoS2/H2O) flow and the hybrid nanofluid (MoS2–SiO2/H2O–C2H6O2) flow between the parallel plates and their heat transport property. The heat transport phenomenon is analyzed with the magnetic field, thermal radiation, heat source/sink, suction/injection effect, and porous medium. In the present model, the plate situated above is in the movement towards the lower plate, and the latter is stretching with a linear velocity. The prevailing PDEs depicting the modeled problem with the aforementioned effects are transformed via similarity transformations and solved via the “bvp4c” function, which is an inbuilt function in MATLAB software. The control of the factors on the fields of velocity and temperature, heat transfer rate, velocity boundary layer patterns, and streamlines is investigated. The solution profiles are visually shown and explained. Furthermore, the Nusselt number at the bottom plate is larger for the (MoS2–SiO2/H2O–C2H6O2) hybrid nanofluid than for the (MoS2/H2O) nanofluid flow. In the presence of suction/injection, the streamlines appear to be denser. In addition, the magnetic field has a thinning consequence on the velocity boundary layer region. The results of this study apply to several thermal systems, engineering, and industrial processes, which utilize nanofluid and hybrid nanofluid for cooling and heating processes.

Molecular dynamics study on the contribution of anisotropic phonon transmission to thermal conductivity of silicon

The analysis of the contribution of anisotropic phonon transmission to thermal conductivity is helpful to focus on high-energy phonons in heat transport. We calculated a series of anharmonic phonon properties and heat transport properties of Si by Fourier projection method from atomic trajectories. Under this theoretical scheme, we have obtained very consistent results with the experimental data through very low computational cost, especially the anharmonic phonon properties at high temperature. We carefully analyze the contribution of different phonons to thermal conductivity and the anisotropic feature of phonon. It is found that the longitudinal acoustic (LA) phonons have the special thermal broadening near the point L at the boundary of the Brillouin zone. The optical phonons cannot be safely ignored in the study of heat transport, especially the longitudinal optical phonon that shows a large contribution to thermal conductivity at room temperature. The thermal conductivity contribution of different phonons varies with temperature. The anisotropic features of the contribution of different phonons to thermal conductivity are mainly reflected in the short-wavelength phonons. Our work explains the reason why other research works have different opinions on whether LA phonon is the main contributor of thermal conductivity. These investigations also provide insights for further understanding phonon heat transport and distribution of high-energy phonons.

Tunability of the thermal diffusivity of cellulose nanofibril films by addition of multivalent metal ions

Discovering principles to tune the heat-transport properties of cellulose nanofibril (CNF) films will open the door for the development of biomass-derived heat-transfer materials and break away from existing petroleum-based polymer composites. In this study, we added various multivalent metal ions to CNF films with surface carboxy groups formed by 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) oxidation and measured their thermal diffusivities in the dry state by an original method to verify the tunability of the thermal diffusivity. We found that the in-plane thermal diffusivity of the film is inversely proportional to the ionic radius and directly proportional to the Pauling electro-negativity. The CNF film with proton-neutralized carboxyl groups showed the highest level of thermal diffusivity among the films with various metal ions. Molecular dynamics simulations clarified that the spatial distribution of the introduced ions is determined by the closest distance between the cation and carboxylate oxygen atom of the TEMPO-oxidized CNF surface.

Statistical analysis of viscous hybridized nanofluid flowing via Galerkin finite element technique

BackgroundBecause of its industrial applications, heat transmission is critical. A novel nanofluid class known as “hybrid nanofluid” is being employed to improve the heat transfer capacities of regular fluids and has a greater heat exponent than nanofluids. Two-element nanoparticles submerged in a base fluid are involved with the hybrid nanofluids. In this study, the hybrid nanofluid flowing and heat transport properties of a slippery surface are explored. PurposeThe goal of this study is to investigate the steady stream and energy transfer of hybridizing nanoparticles across a surface with radiative impacts. To turn the leading equations into a place of comparable equations, a corresponding conversion is utilized. DesignThe thermal and flow characteristics of Powell-Eyring hybridizing nanofluids (PEHNF) were examined in this study under the influence of unsteadiness, porous material, variable thermal conductivity, thermal radiation, and convective boundary conditions. To evaluate the effectiveness of CNF, two different nanoparticles (Copper (Cu) and Titanium oxide (TiO2) are used, together with engine oil (EO) as a base fluid. The mathematical flow modeling of the nanofluid might be finished using a single-phase model and entropy evaluation. MethodologyTo solve the issue analytically, the COMSOL computing tool employs the Galerkin finite element technique (G-FEM). Tables and graphs demonstrate the results of several identifying, including the local Nusselt number, friction factor coefficients, rapidity, temperature, and entropy. FindingsThe results demonstrate that increasing the Casson parameter decreases the temperature profile, while varying the Biot number, thermal radiative, and variable thermal conductivity parameter has no effect. The flow rapidity is lowered when the highly permeable material factor and volume fractions of nanoparticle are estimated to be bigger. The entropy of the system increases as the volume proportion of nanoparticles, thermal radiation, Powell-Eyring parameter, Biot number, and Reynolds number increase. Lamina form nanoparticles have a greater influence on temperature and entropy functions than sphere, hexahedron, tetrahedron, or column shape nanoparticles. The heat transfer ratio of PEHNF (Cu-TiO2/EO) was much larger than that of standard nanofluids (Cu-EO). OriginalityThe recent research examined the effect of using hybridizing nanofluid in diverse thermal management applications using experimental and simulation analysis. The acquired findings proved the efficacy of nanofluid treatment.

Melting heat phenomenon in thermally stratified fluid reservoirs (Powell-Eyring fluid) with joule heating

The currant study focuses on the characteristics of melting heat phenomenon in the Powell-Eyring fluid flow deformed by the linearly stretchable sheet in the vicinity of stagnation point. Quadratic thermal stratification, thermal radiation, viscous dissipation and Joule heating are implemented to disclose the heat transport properties. Magnetic field is implemented to the fluid with an angle α. Mass diffusion is scrutinized through quadratic solutal stratification and constructive/ destructive chemical reactions. A system of dimensionless governing equations are achieved through appropriate transformations. Physical behaviors of temperature, velocity and concentration fields are elaborated through graphs. Skin friction, entropy generation, rates of mass and heat transfer are disclosed through graphs corresponding to pertinent parameters. Decrease occurs in temperature field for dominant melting and thermal stratification phenomenon. Entropy has inverse behavior in case of dominant thermal stratification while similar behavior of melting case. The interesting behavior in melting heat transfer phenomena is the increase of temperature as we raise the Prandtl number. Also, it is worth mentioning that the velocity outline accelerated and temperature profile decelerated with the enhancement of melting factor.

Systematic study on thermal conductivity of organic triangular lattice systems β′-X[Pd(dmit)2]2

Systematic variation of the low-temperature heat transport properties of the quasi-two-dimensional quantum spin liquid (QSL) candidate ${\ensuremath{\beta}}^{\ensuremath{'}}\text{\ensuremath{-}}{\mathrm{EtMe}}_{3}\mathrm{Sb}[\mathrm{Pd}({\mathrm{dmit})}_{2}{]}_{2}$ and its analog compounds showing antiferromagnetic (AFM) ordering is discussed using thermal conductivity $\ensuremath{\kappa}$ measurements. All compounds with the QSL ground state show a monotonic decrease in $\ensuremath{\kappa}$ with decreasing temperature, which is a typical feature of glass or amorphous materials, caused by their low-energy phonon structures. In contrast, the AFM compounds exhibit a peak structure of $\ensuremath{\kappa}$ around 10 K, which is the characteristic temperature dependence of normal crystals with coherent phonons. Our results indicate that the anomalous glassy behavior in ${\ensuremath{\beta}}^{\ensuremath{'}}\text{\ensuremath{-}}{\mathrm{EtMe}}_{3}\mathrm{Sb}[\mathrm{Pd}({\mathrm{dmit})}_{2}{]}_{2}$ is an intrinsic and universal feature of the organic QSL phase and is not caused by extrinsic factors, such as the quality of the samples and the microcracks occurring during the cooling process. We propose a scenario for the origin of the glassy behavior of QSL compounds in which the charge fluctuation within the Pd(${\mathrm{dmit})}_{2}$ dimers changes the phonon properties from crystalline to glasslike.

Exploring the Impact of the Linker Length on Heat Transport in Metal-Organic Frameworks.

Metal–organic frameworks (MOFs) are a highly versatile group of porous materials suitable for a broad range of applications, which often crucially depend on the MOFs’ heat transport properties. Nevertheless, detailed relationships between the chemical structure of MOFs and their thermal conductivities are still largely missing. To lay the foundations for developing such relationships, we performed non-equilibrium molecular dynamics simulations to analyze heat transport in a selected set of materials. In particular, we focus on the impact of organic linkers, the inorganic nodes and the interfaces between them. To obtain reliable data, great care was taken to generate and thoroughly benchmark system-specific force fields building on ab-initio-based reference data. To systematically separate the different factors arising from the complex structures of MOF, we also studied a series of suitably designed model systems. Notably, besides the expected trend that longer linkers lead to a reduction in thermal conductivity due to an increase in porosity, they also cause an increase in the interface resistance between the different building blocks of the MOFs. This is relevant insofar as the interface resistance dominates the total thermal resistance of the MOF. Employing suitably designed model systems, it can be shown that this dominance of the interface resistance is not the consequence of the specific, potentially weak, chemical interactions between nodes and linkers. Rather, it is inherent to the framework structures of the MOFs. These findings improve our understanding of heat transport in MOFs and will help in tailoring the thermal conductivities of MOFs for specific applications.

Thermal transport in two-dimensional nematic superconductors

We study the thermal transport in a two-dimensional system with coexisting superconducting (SC) and nematic orders. We analyze the nature of the coexistence phase in a tight-binding square lattice where the nematic state is modelled as a $d$-wave Pomeranchuk-type instability and the feedback of the symmetry breaking nematic state on the SC order is accounted for by mixing of the $s, d$ paring interaction. The electronic thermal conductivity is computed within the framework of Boltzmann kinetic theory where the impurity scattering collision integral is treated in the Born and unitary limits. We present qualitative, analytical, and numerical results that show that the heat transport properties of SC states emerging from a nematic background are quite distinct and depend on the degree of anisotropy of the SC gap induced by nematicity. We describe the influence of the Fermi surface topology, the van Hove singularities, and the presence or absence of zero-energy excitations in the coexistence phase on the the low-temperature behavior of the thermal conductivity. Our main conclusion is that the interplay of nematic and SC orders has visible signatures in the thermal transport, which can be used to infer SC gap structure in the coexistence phase.

Effect of gamma irradiation on the critical heat flux of sintered nano-coated surfaces

The electrophoretic deposition (EPD) technique was used to manufacture uniform SiO2, Al2O3, ZrO2, and TiO2 thin film coatings on thin steel plates (1.5 mm by 90 mm) to study heat transport properties when in contact with water at boiling temperature. To find the thickness and uniformity of the coatings, scanning electron microscope (SEM) images were made. The captured images showed that the coating thickness is uniformly increased by the EPD method. To investigate the effect of sintering, the coated plates were placed in a furnace at various temperatures. To investigate the effect of gamma irradiation on the critical heat flux (CHF) of the coated surfaces, the test specimens were irradiated in a gamma cell with different dose rates, and then BET, SEM, and EDS analyses were performed. Significant enhancement in CHF, for the hydrophilic surfaces, can be achieved by the EPD method. The results showed that the CHF for the sintered nano-coated surfaces, SiO2, Al2O3, ZrO2, and TiO2, increase by 24%, 23%, 19%, and 10%, compared to those of unsintered nanocoated surfaces, respectively. It was observed that irradiation significantly decreases the maximum pore diameter while it increases the porosity, pore surface area, and pore volume. The CHF of the nano-coated surfaces irradiated at 300 kGy increased by 12%, 8%, 5%, and 12% for SiO2, Al2O3, ZrO2, and TiO2, respectively. Nevertheless, the effect of gamma irradiation on the sintered surfaces was insignificant.

Effects of Different Phonon Scattering Factors on the Heat Transport Properties of Graphene Ribbons.

Understanding the effect of phonon scattering is of primary significance in the study of the thermal transport properties of graphene. While phonon scattering negatively affects the thermal conductivity, the exact effect of microscopic phonon scattering is still poorly understood when full phonon dispersions are taken into account. The heat transport properties of graphene ribbons were investigated theoretically by taking into account different polarization branches with different frequencies in order to understand the physical mechanism of the thermal transport phenomenon at the nanoscale. The effects of grain size, chiral angle, Grüneisen anharmonicity parameter, specularity parameter, and mass-fluctuation-scattering parameter were evaluated, taking into account of the restrictions imposed by boundary, Umklapp, and isotope scattering mechanisms. The contribution from each phonon branch was estimated, and the anisotropic coefficients were determined accordingly. The results indicated that the graphene ribbons are very efficient at conducting heat in all the cases studied. All the acoustical branches contribute significantly to the heat transport properties, and the temperature strongly affects the relative contribution of the phonon branches. The lattice thermal conductivity varies periodically with the chiral angle. The maximum thermal conductivity is achieved in the zigzag direction, and the minimum thermal conductivity is obtained in the armchair direction. The lattice thermal conductivity and anisotropic coefficient depend heavily upon the roughness of the edges and the width of the ribbons. The specularity parameter and mass-fluctuation-scattering parameter significantly affect the lattice thermal conductivity, and the effect arising from isotope scattering is significant in the context of natural isotopic abundance. The dependence of the Grüneisen anharmonicity parameter on phonon branches must be taken into account when making predictions. The results have significant implications for the understanding of the relations between phonon scattering and thermal properties.

Synthesis, structure and transport properties of high-pressure modification VO2(S)

A new high pressure modification VO2(S) was obtained by the thermobaric treatment of stoichiometric mixture of powders V2O3+V2O5 at Р = 2.0–7.0 GPa and Т = 600–900°С. The crystal structure of VO2(S) has been studied using X-ray powder diffraction: a = 7.35367(3), c = 4.51507(4) Å, V = 211.448(1) Å3 at T = 296(1) K, Z = 7, space group P3. The V atoms are six-coordinated within distorted VO6 octahedra. The structure is double-layered and built up of triple units of edge-shared octahedra. The connection of these units forms one solid layer, while the second one contains separate units. Structural relationships between VO2(S), VO2(M2) and WO2-hp are discussed. Electric and X-ray diffraction measurements show that VO2(S) undergoes a weak first-order phase transition at temperature around 290 K. We also carried out density functional calculations of VO2(S) using the hybrid HSE06 exchange-correlation functional. The charge and heat transport properties are evaluated within the semi-classical Boltzmann approach.

Heat transport properties within living biological tissues with temperature-dependent thermal properties

Understanding of the heat transport within living biological tissues is crucial to effective heat treatments. The heat transport properties of living biological tissues with temperature-dependent properties are explored in this paper. Taking into account of variable physical properties, the governing equation of temperature is first derived in the context of the dual-phase-lags model (DPL). An effective method, according to the Laplace transform and a linearization technique, is then employed to solve this nonlinear governing equation. The temperature distribution of a biological tissue exposed to a pulsed heat flux on its exterior boundary, which frequently happens in various heat treatments, is predicted and analyzed. The results state that a lower temperature can be predicted when temperature dependence is considered in the heating process. The contributions of key thermal parameters are different and dependent on the ratio of phase lag and the amplitude of the exterior pulsed heat flux.

Heat transfer analysis on Engine oil-based hybrid nanofluid past an exponentially stretching permeable surface with Cu/Al2O3 additives

The flow characteristic of the two-dimensional conducting hybrid nanofluid past an exponentially stretching permeable surface is analyzed. Flow through variable thicker surface for the free convective flow associated with transverse magnetic field in the flow phenomenon that enriches the study. The specialty of the model is the use of effective conductivity property considering the Mintsa model and the effective viscosity with the help of the Gharesim model for the enhancement of heat transport properties. Depending upon the recent applications related to industrial products, engineering as well as bio-medical science nanofluids are used as the best coolant. A comparative study is carried out for the transformed governing equations using both approximate analytical, that is, “ Variational Iteration Method” (VIM), “ Homotopy Perturbation Method” (HPM), and numerical techniques such as the in-build MATLAB command bvp5c. The simulated result in connection to the behavior of the physical parameters is deployed through graphs. The current outcomes validate the earlier established results in particular cases showing the conformity and the convergence of the methodology adopted. However, the observation shows that, shear rate retards with the significant enhancement in the particle concentration of the metal nanoparticles as well as the suction further the heat transfer rate enhanced. The fluid velocity profile boosts up for the increasing thermal buoyancy parameter whereas the reverse impact is rendered in the fluid temperature.

Thermal lagging effect on heat transport within living biological tissues

Thermal lagging effect on heat transport within living biological tissues is explored in the context of different relaxation mechanisms. The governing equations of temperature rooted the delay effect between heat flux and temperature gradient, as well as non-equilibrium effect between blood vessel and peripheral tissues, are constructed separately via the classic dual-phase lag model (DPL) and generalized dual-phase lag model (GDPL). An analytical procedure based on the Laplace transform technique and its limit theorem is then proposed. The expressions and effective values of phase lags rooted different effect have been derived and further estimated. On this basis, the temperature response of a biological tissue with its boundary exposed to a pulse heat flux is analyzed. The detailed parametric study has been conducted to explore the dependence of these phase lags on tissue structures and their effect on heat transport properties. The results highlight the contributions of the delay effect and non-equilibrium effect in temperature prediction and state that the delay effect is dominated for a larger tissue size. Meanwhile a significant difference has also been observed with the boundary conditions that obey different thermal conduction mechanism.

Effect of tempering on the metallurgical, structural, and thermal properties of AISI/SAE 1030 steel

Steel exhibits changes in their phase structure; in the thermal and mechanical properties due to thermal treatments. This work analyzed the influence of tempering temperature on these properties for 1030 steel. Samples were quenched at 850 ºC. Then, they were tempered for 2 h at 200 (QT200), 400 (QT400), 600 (QT600), and 650 ºC (QT650). Thermal, structural, morphological, and mechanical properties of these samples were analyzed and correlated. SEM images show changes in martensite morphology and the carbides presence as a function of tempering temperature. QT600 and QT650 samples with high tempering temperature exhibit the highest presence of carbides. X-ray diffraction shows no changes in the steel structure, but changes in lattice parameters, and crystalline quality improvement. Thermal diffusivity was determined and correlated with the structural changes by temperature effect. The heat transport properties increase as a function of the tempering temperature due to in part because of the structural reorganization, which allows heat transport. Due to the crystal stress release and the martensite tempered the hardness decreases as a function of the tempering temperature.

Chemical reaction impact on MHD dissipative Casson-Williamson nanofluid flow over a slippery stretching sheet through porous medium

In this study, we investigated the heat and mass transport properties of a non-Newtonian Casson-Williamson nanofluid flow. We explore the effect of viscous dissipation and the velocity slip boundary condition on the mechanism of heat and mass transfer due to a stretching sheet which embedded in a porous medium with heat generation under the influence of both thermal radiation and a uniform magnetic field. All physicochemical characteristics of Casson-Williamson nanofluid are considered to be constant. The nanofluid concentration is investigated under chemical repercussions as a result of the movement of the nanofluid particles. This study assumes that there is no suction (solid wall). A set of nonlinear partial differential equations with boundary conditions are used to mathematically model this physical problem. The numerical solution for the differential equations with the related boundary conditions was illuminated using the Runge–Kutta approach in conjunction with the shooting technique. The numerical examination is then pictorial displayed to show the impact of various governing factors on velocity, temperature, and concentration. The non-Newtonian nanofluid has a faster velocity in the absence of a magnetic field than in the presence of it, although the temperature field has the opposite trend. Further, the skin-friction coefficient increased as the porosity parameter increased, whereas the rate of heat transfer dropped.

Entropy analysis of radiative [MgZn6Zr-Cu/EO] Casson hybrid nanoliquid with variant thermal conductivity along a stretching surface: Implementing Keller box method

Heat transfer is critical due to its broad application in a variety of industries. New hybrid nanofluids are being used to improve the heat transfer competencies of ordinary fluids and have an enormous exponent heat than nanofluids. Hybrid nanofluids, a novel form of nanofluid, are being utilized to improve the heat transfer capacities of regular fluids and have a more outstanding heat exponent than nanofluids. Two-element nanoparticles submerged in a base fluid make up the hybrid nanofluids. Flow and heat transport properties of a hybrid nanofluid across a slick surface are studied in this study. Nanoparticle shape analysis, porous media, thermal conductance variations, and thermal radiative effects are all part of the process. A numerical approach called the Keller box method is used to solve the governing equations numerically. EO-Engine Oil has been used as a rich, viscous base fluid in this study, and a Cason hybrid nanofluid was examined. This fluid contains two diverse forms of nanoparticles: Copper (Cu) and Magnesium Zinc Zirconium alloy (MgZn6Zr). Compared to standard Cu-EO nanofluids, the heat transmission level of such a fluid (MgZn6Zr-Cu/EO) has steadily increased, which is an important finding from this study. The boundary-lamina-shaped layer's components have the highest thermal conductivity, while sphere-shaped nanoparticles have the lowest. When nanoparticles are assimilated, the entropy of the system increases by a factor of three: their ratio by fractional size, their radiative properties, and their thermal conductivity variations.
