Integrating ISPH simulations with machine learning for thermal radiation and exothermic chemical reaction on heat and mass transfer in spline/triangle star annulus

This work integrates incompressible smoothed particle hydrodynamics (ISPH) with machine learning (ML) to examine the uses of two different domain shapes, spline star-domain, and triangle star-domain, on double diffusion of nano-encapsulated phase change material (NEPCM). The effects of thermal radiation and exothermic chemical reactions are conducted in this work. The hexagonal-shaped is located inside the center of the star-shape carrying (Th&Ch). The left/right walls of the star shape are kept at (Tc&Cc) and the other walls have an adiabatic condition. It is recommended to examine the smoothness of closed curves in the heat and mass transfer by changing the triangle to spline curves. The present investigations of transmission of heat and mass of NEPCM within a complicated star shape can be employed in cooling systems of electronic/battery, heat exchangers, food processing, and chemical engineering. The ISPH simulations are executed for the pertinent parameters, Darcy number, Frank-Kamenetskii number, Rayleigh number, Dufour number, Soret number, and thermal radiation parameter. The performed simulations showed the significance of the spline star domain compared to the triangle star domain in smoothening the nanofluid flow and double-diffusive convection in an annulus. Frank-Kamenetskii number is a promising factor in the enhancement of heat transfer and controlling the phase change zone within an annulus. At a spline-star cavity, the maximum velocity rises by 32.32 % and 54.95 % when the Frank-Kamenetskii number grows from 0 to 5, and thermal radiation increases from 0 to 5. Soret number works effectively in enhancing the distribution of concentration at large temperature differences. Machine learning plays a vital role in many engineering applications. Hence, ML's powerful capabilities to predict the average Nu‾ and Sh‾. In the proposed ML model, the dimensionless time and thermal radiation parameter are used as input to the ML model, while their corresponding numeral estimated values of Nu‾ and Sh‾ are used as output targets for the ML model. The values of Nu‾ and Sh‾ are predicted by the suggested ML model with a comparatively small error less than 1 %.

Dual convection of NEPCM inside an annulus between two circular cylinders mounted on rectangles

This paper adopts the incompressible smoothed particle hydrodynamics (ISPH) method for simulating the dual diffusion of nano-encapsulated phase change material (NEPCM) in an annulus. Here, the novelty is appearing in simulating the double diffusion of NEPCM within a novel complex shape composed from the paradigm of an annulus between two circular cylinders mounted on rectangles. The ISPH method solved the regulating equations of a physical problem. The scales of parameters are a fusion temperature θf(0.05≤θf≤0.95), buoyancy ratio 0≤N≤10, nanoparticle parameter 0.01≤φ≤0.05, a radius of a circular cylinder 0.1≤rc≤0.4, Darcy parameter 10-2≤Da≤10-5, and Rayleigh's number 103≤Ra≤106. The performed simulations showed that the different boundary conditions amongst an inner blockage and outer cavity walls are affecting the strength of concentration and temperature. The location of a phase change zone is varied according to the variations of variable boundary conditions and fusion temperature. The mean Nusselt and Sherwood numbers are improving under an enlargement in a radius of an internal circular cylinder, and Rayleigh numbers.

Laminar forced convection in a tube with a nano-encapsulated phase change materials: Minimizing exergy losses and maximizing the heat transfer rate

The present work investigates the potential of NEPCM mixtures via analyses of convective heat transfer and exergy losses, and trade-offs between them inside a tube with a constant wall temperature. Experimental data for viscosity and thermal conductivity of the mixture was used within numerical simulations over a broad range of dimensionless parameters, including Reynolds number, mass fraction, melting strength, phase change zone thickness, and location of phase change zone. The effect of these parameters on the melting process, convective heat transfer and exergy loss is evaluated. The findings indicate that, although employing a NEPCM can boost the Nusselt number and heat transfer rate by 9.3 % and 16.1 %, as compared to the water, the exergy losses were enhanced up to 17 %. Additionally, in some circumstances, the Nusselt number and heat transfer rate both increased by 5.9 % and 2.5 %, respectively, whereas the exergy losses were zero. An optimal value of ω=0.02 was found to provide reasonable improvement in heat transfer rate increase with no exergy losses. Importantly, the present study shows that although higher NEPCM mass fractions can continue to increase the heat transfer performance, their benefit is rapidly offset above ω=0.02 due to heat transfer related exergy losses. Additionally, it was concluded that, in comparison to other parameters, the location of the phase change and the mass concentration of NEPCMS substantially affected the percentage of molten NEPCM and the latent heat efficacy.

Transpiration cooling with phase change by functionally graded porous media

Transpiration cooling using liquid coolants is considered one of the most promising thermal protection techniques for new generation aerospace vehicles. The leading edges are subjected to a very high and non-uniform heat flux. Unfortunately, few coolants can flow through the part near the stagnation point using traditional porous structures, which will cause ablation. Unlike conventional fabrication methods, additive manufacturing is capable of directly tailoring porous structures with well-controlled pore features and functional graded pore topology, thereby optimizing the coolant distribution and improving the cooling performance. Smoothly graded pore structures can be fabricated using additive manufacturing technology. We experimentally assessed the transpiration cooling performance of uniform and graded porosity porous plates to compare the coolant distributions, temperature profiles, and features of the two-phase region. Graded porous media exhibited much better cooling performance than uniform pore topology. Through computations, the graded porosity improved the imbalanced coolant distribution and minimized the hot-spot temperature under a non-uniform heat flux. Importantly, the temperature profile at the outlet should match with the local flow resistance in porous media and the heat flux at the outlet. The temperature and phase change zone were highly dependent on the topology of the porous media, heat flux profile applied to the outlet, and coolant mass flow rate.

EFFECTS OF MAGNETIC FIELD AND THERMAL RADIATION ON DOUBLE DIFFUSION OF A SOLID PHASE IN THE TWO CONNECTED CIRCULAR CYLINDERS SUSPENDED BY NEPCM AND POROUS MEDIA

The novelty of the present work is studying the influences of thermal radiation and magnetic field on the double diffusion of solid phase in the novel cavity of two linked cylinders suspended by nano-encapsulated phase change materials (NEPCMs) and porous media. The complex cavity contains two circular cylinders connected by an open gate occupied by solid particles. Two different boundary conditions including hot and cold for the solid phase are conducted in this work. The incompressible smoothed particle hydrodynamics (ISPH) method is improved to solve the time-fractional governing equations of the physical problem. The mesh-free nature of the ISPH method helps in treating the different materials of the solid and fluid phases efficiently. The physical parameters are dimensionless time parameter τ, Hartmann number Ha, thermal radiation parameter Rd, fractional time-derivative α, Darcy parameter Da, Rayleigh number Ra, and fusion temperature θ<sub>f</sub>. The main findings of the numerical simulations indicated that the fractional time-derivative parameter changes the transmission of heat-mass and nanofluid developments during the initial time steps. The Rayleigh number works well in improving the interactions between the solid and fluid phases due to the high buoyancy forces. Increasing the Rayleigh number improves the intensity of the temperature, concentration, and nanofluid speed in a cavity at Case 1 (C1) and Case 2 (C2). The phase change zone is changing according to the alterations of boundary conditions, Rayleigh number, and fusion temperature. Increasing thermal radiation parameter shrinks the nanofluid movements and mean Nusselt number Nu.

Conjugate free convection from an array of discrete heat sources with water and nano-encapsulated phase change particle in a cold enclosure

The present works investigates the conjugate free convection in a cold enclosure containing a hot circular cylinder. An array of discrete heat sources are attached to the cylinder surface. The free space between the enclosure and the cylinder was filled with a heterogeneous mixture of water and nano-encapsulated phase change particle (NEPCP). This nanoparticles have an outer shell and a core inside. Specifically, the NEPCP core can absorb thermal energy on charging state or releases energy on discharging state. The governing parameters considered are the number of heated segment, 1≤n≤4, the heat source thickness, 0≤A≤0.1, the fusion temperature, 0.1≤Θf≤0.5, the heating intensity, 104≤Ra≤106, and the NEPCP concentration, 0≤ϕ≤0.05. The results shows that the Θf, n, A, and Ra modify the position and size of the area of phase change zone. The maximum Nusselt number was found at different angular positions depending on the heat source arrangement. The maximum value increases by increasing the NEPCP concentration, but its position almost unchanged by adjusting the concentration. There is critical A=Ac and max(ϕ) for the optimum arrangement of discrete heat source.

Receiving heat from a PCM tank by using natural convection of water and NEPCM: A simulation for LHTES application

Latent heat thermal energy storage (LHTES) systems are widely used due to their ability to store a lot of heat energy as latent, and few studies have directly or indirectly investigated on the heat exchange methods with LHTES systems. In the present study, the free convection of a mixture of water and Nano-encapsulated phase change material (NEPCM) with a porous medium was used to exchange heat energy between a cold-water stream and a hot tank filled phase change material (PCM). NEPCM are nanostructures consisted of a solid shell and a PCM core, and the addition of these nanostructures to water has remarkable effects on the heat transfer parameters. In this research, a number of cases were simulated using computational fluid dynamic (CFD) to observe the impacts of injecting NEPCM to water, the porosity of the porous media and the location of the phase change zone on the average heat flux of the PCM tank. The results showed that increment of porosity number from 0.85 to 0.95 decreased the average heat flux of the PCM tank by 13.8%. Moreover, adding 3% NEPCM to water enhanced the average heat flux of the PCM tank by 22.2% and 18.4% when porosity numbers were 0.85 and 0.95, respectively.

Simulation of a new phase change energy storage tank design with a vertical baffle

In this study, a new phase change water tank (NPCWT) design with a vertical baffle was simulated. Unlike in traditional phase change water tank (TPCWT) designs, the phase change materials (PCMs) of the new design were concentrated on one side of the tank, and the baffle divides the tank into a phase-change zone and a non-phase change zone. The simulation results were first compared with experimental data to verify the accuracy of the simulation. Then, the FLUENT software package was used to compare the performance of the NPCWT with that of a common water tank (CWT) and a TPCWT of the same overall dimensions. The influence of the inlet flowrate on NPCWT performance was also studied. The heat storage and release performance of tanks were analyzed in terms of heat storage and release time, temperature distribution, and the utilization rate of the PCM. The simulation results show that the performance of the NPCWT is better than that of the other two designs. Compared with TPCWT, the heat storage time is reduced by 4.12%, while the heat release time is extended by 4.6%. It can also effectively solve the problem of the low utilization rate of PCM, and the heat storage capacity and other parameters are improved. The overall thermal performance of the NPCWT is at an optimum when the inlet flow rate is set to 0.2–0.3 m/s.

Effects of thermal radiation on natural convection in two connected circular cylinders suspended by NEPCM and porous media

The natural convection of NEPCM was delivered in the closed cavity constructed from two circular cylinders. The contributions of the NEPCM particles in heat transfer are achieved by the phase change. The partial differential equations that govern a nanofluid motion and heat transport are solved by a time fractional derivative of ISPH method. The impacts of the pertinent parameters, thermal radiation parameter Rayleigh number Darcy parameter Fusion temperature length of a hot source and fractional time-derivative on the nanofluid flow and heat transfer are discussed. The main findings indicated that the Rayleigh number is representing a well role in improving the nanofluid movements and intensity of the temperature within the two circular cylinders. The phase change zone is reducing by an increase in Rayleigh number. The higher nanofluid speed and heat transfer are higher at the top cylinder compared to the bottom cylinder. Increasing the length of a hot source enhances the temperature strength within a cavity.

Thermal response analysis and parameter prediction of additively manufactured polymers

Fused Deposition Modelling (FDM), is an additive manufacturing technology where polymers are extruded using appropriate processing parameters to achieve suitable bonding while ensuring that overheating does not occur. Among processing parameters, polymer inlet temperature, nozzle size, extrusion speed, and air cooling speed are significantly effect on the extrusion process at the distance between the build plate and the nozzle tip (standoff region). This study aims to evaluate the influences of the processing parameters on the thermal behavior and phase change zone of Polyamide 12 (PA12) and Acrylonitrile Butadiene Styrene (ABS) polymers at standoff region. A nonlinear three-dimensional (3D) finite element (FE) model was developed by implementing an apparent heat capacity model using the Heat Transfer Module in COMSOL® Multiphysics software. FE results in the standoff region were validated by experimental tests, concerning various nozzle sizes and extrusion speed. The validated numerical results demonstrated that there is a complex correlation between processing parameters and thermal behaviors such as phase change and temperature distribution in the standoff region. The FE results were then employed in training an artificial neural network (ANN). A well-established compromise between the trained ANN and the FE results demonstrates that the trained ANN can be employed in the prediction of further thermal and glass transition behavior using subsequent processing parameters.

Thermal management and natural convection flow of nano encapsulated phase change material (NEPCM)-water suspension in a reverse T-shaped porous cavity enshrining two hot corrugated baffles: A boost to renewable energy storage

Renewable energy systems may be turning to be more effectual and inexpensive and contributing lion's share of whole energy utilization in today's power hungry planet. The efficacious usage of solar energy needs a storage appliance which could simplify the storage of surplus energy, and finally provide such energy when it desires. One of the efficacious approach of storing thermic energy of higher density from renewable source is executed in a varying range of temperature positions by phase change materials (PCMs) or nano encapsulated phase change material (NEPCM) as their significant role in air-conditioning systems, thermal energy storage, computer chipsets, and thermal management of buildings. In view of this, the present investigations aims at natural convection flow, heat transfer, and entropy of NEPCM-water suspension in a reverse T-shaped porous cavity enshrining two hot corrugated baffles. The thermal control within the cavity is maintained by hot corrugated baffles, cooling of bottom and upper walls and managing the side walls as adiabatic. The governing equations are well established and converted into dimensionless structure and then solved subsequently by Finite Element method (FEM). Simulated outcomes might well be validated accurately and the influence of Rayleigh number (104≤Ra≤106), porosity (0.4≤ε≤0.8), Darcy number (10−4≤Da≤10−2), NEPCM particle volume fraction (0≤φ≤5%), length of the corrugated walls (0.10L≤b≤0.20L), and fusion temperature (0.2≤θf≤0.8) on the heat transfer features, isotherms, heat capacity ratio and streamlines is explored efficaciously. The outcomes of this study are that amplifying Raleigh number leads to the intensification of streamlines, velocity fields and structural change of phase change zone while decaying of Darcy number exhibits the opposite effect. Strengthening porosity of porous medium intensifies the streamlines, horizontal and vertical velocity. Growth of the length of baffles yields emaciation of streamlines, flow fields, and enormous rate of heat transfer. Heat capacity ratio attains a constant value 0.97 outside melting-solidification zones within the cavity. Rise in the fusion temperature results in the expansion and shifting of melting-solidification zone. When φ rises from 1% to 2%, Nuave uplifts and yields its minimum enhancement while with rise of φ from 1% to 5%, Nuave upgrades and yields its maximum enhancement at fixed Darcy and Raleigh numbers.

The conformable fractal systems of natural convection in an annulus suspended by NEPCM

The incompressible smoothed particle hydrodynamics (ISPH) method is improved by the Taylor expansion to manage the unsteady conformable fractal systems of natural convection within a porous annulus amongst the circular cylinders. The annulus is suspended by a nano-encapsulated phase change material (NEPCM). The inner circular cylinders are fixed at a cool temperature. The ISPH numerical investigations are performed for variable values of the conformable fractal parameter α (0.93 − 1), adiabatic length LAdiab(0.5 − 2), Darcy parameter Da (10−2 − 10−5), thermalradiation parameter Rd (0 − 5), Rayleigh number Ra (103 − 106), the radius of an inner cylinder RCylind(0.15 − 0.4), and the fusion temperature θf (0.05 − 0.75). The outcome results indicated the novel significance of the conformable fractal parameter in speeding the transition process to a stable condition. The changes in the thermal boundary conditions of the outer walls by altering the adiabatic length affect the temperature distributions, phase change zone, and nanofluid velocity. Increasing thermal radiation improves the isotherms and shrinks a phase change zone. The fusion temperature has a good role in adjusting the situation and power of a phase change zone within a cavity. Contributions of Rayleigh number are less in enhancing convection and phase change zone due to a small area of an annulus. Rayleigh number strengthens the nanofluid velocity in an annulus.

Heat transfer improvement between a pair of heater and cooler inside an energy storage by using nano-encapsulated phase change material/water: A numerical modeling

In the present study, the natural convection flow of water with Nano-encapsulated phase change material (NPCM) was simulated inside an insulated chamber, which a pair of pipes were considered as a heater and cooler sources with the boundary condition of uniform temperature. The NPCM's core was made of n-nonadecane with melting temperature of 30.44°C. This core has ability to change the liquid-solid phase to transfer heat between the heater and the cooler sources. Current simulation was steady state and was solved by SIMPLE algorithm based on FVM to investigate the effects of Rayleigh number, volume fraction and location of phase change zone on the convective heat transfer coefficient. Observations showed that, phase change of NPCM occurs at low Rayleigh numbers but had no effect on the convective heat transfer coefficient, but it was directly related to the thermal conductivity of mixture. Moreover, adding volume fraction of NPCM 0.02 into water increased the convective heat transfer coefficient by 10.43%, 19.1% and 18.3% compared to pure water for Rayleigh numbers 102,104,and106, respectively.

Double-diffusive convection from an oscillating baffle embedded in an astroid-shaped cavity suspended by nano encapsulated phage change materials: ISPH simulations

The incompressible smoothed particle hydrodynamics is applied to simulate the suspension of the nano-encapsulated phase change materials (NEPCMs) within an astroid-shaped cavity. The astroid signifies a geophysical frontier of scientific significance in a mechanical profile of the solar system’s origin. Hence, a novel geometry of an astroid shape is conducted in this work. An embedded baffle inside an astroid-shaped cavity is oscillating by an excitation motion x = asin ( ωt ) . The oscillating motion of a baffle and double-diffusive convection inside an astroid-shaped cavity are handled by the ISPH method. The astroid-shaped cavity has low temperature and concentration in the bottom walls while the top walls are adiabatic. The numerical simulations clarified that an amplitude parameter of the oscillation motion varies the phase change zone and features of heat and mass transport inside an astroid-shaped cavity. The Stefan and fusion parameters are acting effectively in enhancing a phase change zone. The expanded baffle is utilizing to enhance the convective heat and mass transport and a phase change zone. The superior values of the average Nusselt and Sherwood numbers are obtained when the inner baffle is expanded due to higher buoyancy forces.

Effect of dual-rotation on MHD natural convection of NEPCM in a hexagonal-shaped cavity based on time-fractional ISPH method

The time-fractional derivative based on the Grunwald–Letnikove derivative of the 2D-ISPH method is applying to emulate the dual rotation on MHD natural convection in a hexagonal-shaped cavity suspended by nano-encapsulated phase change material (NEPCM). The dual rotation is performed between the inner fin and outer hexagonal-shaped cavity. The impacts of a fractional time derivative alphaleft( {0.92 le alpha le 1} right), Hartmann number Ha left( {0 le Ha le 80} right), fin length left( {0.2 le L_{Fin} le 1} right), Darcy parameter Da left( {10^{ - 2} le Da le 10^{ - 4} } right), Rayleigh number Ra left( {10^{3} le Ra le 10^{6} } right), fusion temperature theta_{f}left( {0.05 le theta_{f} le 0.8} right), and solid volume fraction varphileft( {0 le varphi le 0.06} right) on the velocity field, isotherms, and mean Nusselt number overline{Nu} are discussed. The outcomes signaled that a dual rotation of the inner fin and outer domain is affected by a time-fractional derivative. The inserted cool fin is functioning efficiently in the cooling process and adjusting the phase change zone within a hexagonal-shaped cavity. An increment in fin length augments the cooling process and changes the location of a phase change zone. A fusion temperature theta_{f} adjusts the strength and position of a phase change zone. The highest values of overline{Nu} are obtained when alpha = 1. An expansion in Hartmann number Ha reduces the values of overline{Nu}. Adding more concentration of nanoparticles is improving the values of overline{Nu}.

Thermosolutal convection of nano–encapsulated phase change materials within a porous circular cylinder containing crescent with periodic side-wall temperature and concentration: ISPH simulation

This work inspects the magnetic influences on the thermosolutal convection of nano–encapsulated phase change materials (NEPCMs) within a circular cylinder including crescent with periodic side-wall temperature and concentration. The incompressible smoothed particle hydrodynamics (ISPH) method based on a Grunwald- Letnikove time derivative is adopted to handle the current physical problem. The circular cylinder is suspended by NEPCM and saturated by a porous medium. Rotation of an inner crescent with a variable frequency has been conducted. The influences of a fractional time derivative from 0.95 to 1, Darcy parameter from to Rayleigh number from to Hartmann number from 0 to 50, a fusion temperature from 0.05 to 0.9, rotation parameter from 1 to 5, amplitude parameter from 0.5 to 2, and frequency parameter from 5 to 100 on the heat capacity, isotherms, velocity field, isoconcentration, and mean Nusselt number and mean Sherwood number are investigated. It is found that an increase in the Hartmann number drops the velocity’s maximum by 21.43%. Increasing a fusion temperature shifts the phase change zone towards the inserted heated crescent. The angular rotation parameter for an inner crescent is changing the heat/mass transport and nanofluid movements within a circular cylinder. The phase change zone is affected by the variations of an amplitude parameter at higher values of the frequency The values of and are increasing as an amplitude parameter boosts.

Natural convection of water and nano‐emulsion phase change material inside a square enclosure to cool the electronic components

The usage of natural convection has many applications for cooling and controlling the temperature of electronic components. Therefore, in the present simulation, the average Nusselt number and maximum temperature of surface's electronic components are studied by adding nano-emulsion phase change material (NPCM) with water as the base fluid. Because, the previous studies show that adding NPCM to a base fluid can increase the specific heat capacity of a mixture in order to change the phase in the solid–liquid transition. The used NPCM consists of n-eicosane as a core and sodium lauryl sulphate as a shell. The geometry includes a square enclosure with the top wall as a cold wall and the bottom wall as a hot electronic component with constant heat flux. In the current study, the effects of Rayleigh numbers (), cold wall temperature (), and volume fraction of NPCM () are investigated to understand the behaviors of NPCM on heat transfer parameters. The observations show that the average Nusselt number is directly related to Rayleigh number and thickness of the phase change zone. Moreover, the optimal value of volume fraction is 0.012 that increases average Nusselt number 7.3% and 5.4% for low and high Rayleigh numbers, respectively.

The magnetic power on natural convection of NEPCM suspended in a porous annulus between a hexagonal-shaped cavity and dual curves

This paper discusses the magnetic powers on the thermosolutal convection of nano-encapsulated phase change material (NEPCM) inside a porous annulus by using the ISPH method. A novel annulus is constructed between an exterior hexagonal-shaped and inner shape of the dual curves having varying lengths (a&b). The heat/mass source is put in the left-top and right-bottom parts of a hexagonal-shaped and the other parts are adiabatic. The inner dual curves are maintained at Tc and Cc. The effects of the inner dual curve lengths (a=0.1−0.4&b=0.2−1), a fusion temperature (θf=0.05−0.95), Darcy parameter (Da=10−2−10−5), Hartmann number (Ha=0−100), solid volume fraction (ϕ=0.01−0.06), time parameter (τ=0−0.8), and Rayleigh number (Ra=103−106) on the contours of heat capacity, concentration, streamlines, temperature, and nanofluid velocity are researched. The results revealed that an increase in a fusion temperature shifts a phase change zone from the dual curves towards the heater source positions. The lengths of the inner dual curves are controlling the contours of the heat capacity, temperature, streamlines, and concentration in an annulus. Thus, the velocity's maximum boosts by 26.92% as length b shrinks from 1 to 0.2. Increasing Ra expands the contours of temperature, concentration, and heat capacity Cr across an annulus.

Double‐diffusive convection in a porous complex‐shaped cavity suspended by nano‐encapsulated phase change materials

AbstractThis paper simulates a double‐diffusive convection of suspended nano‐encapsulated phase change materials (NEPCM) embedded inside a porous complex‐shaped cavity. The ISPH method is employed to handle the controlling equations in dimensionless form. The complex‐shaped cavity consists of a circular cylinder mounted vertically on two rectangle shapes. Variable‐length on the left wall is maintained at a temperature and concentration higher than the on the other side of the wall. Phase changes in encapsulated nanoparticles were assessed by the heat capacity of the core and shell layers. The simulations carried out were shown in terms of the velocity field, temperature, concentration, and melting‐solidification zones below the effects of the variable hot source , the fusion temperature and the Stefan parameter . The main finding indicated that the phase change zone follows the hot source within the cavity. The expansions of the partial hot length and the fusion temperature alter the intensity and location of the phase change zone. An augmentation in the Stefan number lowers the intensity of the phase change zone.

The paper is dedicated to numerical simulation based on a mesh-free method for a double-diffusive flow between two different materials inside a porous infinite-shaped enclosure suspended by a nano-encapsulated phase change material (NEPCM). Controlling equations have been solved by the Incompressible Smoothed Particle Hydrodynamics (ISPH) method. The first phase is considered a mixture of water and NEPCMs, and the second phase is formed by solid particles. Inside the novel shape of an infinite-shaped enclosure, the solid phase is carrying Th and Ch during the whole simulation and the bottom-wall of an infinite shape is kept at is carrying Tc and Cc. Variations of Darcy parameter, fusion temperature, buoyancy ratio parameter, Stefan parameter, and Lewis number on the phase change zone, materials tracking, temperature, velocity field, and concentration are discussed. The results have shown that the fusion temperature disciplines the phase change zone within a porous infinite-shaped enclosure. The Stefan number adjusts the intensity of the phase change zone. The buoyancy ratio and the Darcy parameters are representing as essential factors in controlling the distribution of solid particles within the nanofluid phase. The ISPH method is validated by comparison with practical and numerical results.
