The present work deals with thermal aspect and entropy of ternary hybrid nanofluid (Graphene, Al2O3, MWCNT as nanoparticles water base fluid) inside an inclined domain considering heat generation/absorption. possesses triangle-shaped corrugated walls variable height a semi-circular heater located on its bottom wall. Finite element method (FEM) is employed to acquire well-defined solution the non-dimensional governing equations along boundary conditions. influence pertinent parameters their ranges , has been studied. Some striking outcomes investigation are that streamlines generation peter out while local Nusselt number average Bejan ameliorate rise in dimensionless wall . absolute maximum values vertical horizontal velocities enhance by 96.47% 29.5%, respectively, when inclination angle increases from It visualized subject sink it attains minimum value response source. Because triangle shaped nanofluid, problem contributes superior cooling systems featured such complex geometry industries.

Abstract The current work extensively investigates double‐diffusive of nano‐encapsulated phase change material in a thermal storage system partially filled with porous foam. generation irreversibilities and the influence Soret/Dufour magnetohydrodynamic effects are also considered. circular cold cavity contains corrugated hot cylinder covered by an annular considered parameters Rayleigh number (10 3 –10 5 ), fusion temperature (0.1–0.9), Stefan volume concentration nanoparticles (0–0.05), Darcy −4 −1 ). Hartmann (0–80) undulations inner (3–9). numerical analysis has exploited finite element approximations. results indicate that numbers greatly fluid flow, isotherms, concentrations melting/solidification region. great on region while there is no evident isotherms where both Nusselt Sherwood around 5% number. In contrast, values decreased 30% decreasing Da from 0.1 to 10 . Furthermore, very low heat transfer, mass transfer

Purpose This paper aims to focuses on by investigate the heat transmission and free convective flow of a suspension nano encapsulated phase change materials (NEPCMs) within an enclosure. Particles NEPCM have core-shell structure, with material (PCM) serving as core. Design/methodology/approach The enclosure consists square chamber insulated wall top bottom vertical walls that are differently heated. governing equations investigated using finite element technique. A grid inspection validation test done confirm precision results. Findings effects fusion temperature (varying from 0.1 0.9), Stefan number (changing 0.2 0.7), Rayleigh 10 3 6 ) volume fraction nanoparticles 0 0.05) streamlines, isotherms, capacity ratio average Nusselt graphs tables. From this investigation, it is found results in significant enhancement transfer compared pure fluid. augmentation becomes more important for low number, which around 16.57% approximately at 0.2. Secondary recirculation formed near upper left corner result non-uniform heating border. eddy expands notably rises. study findings indicate nanosuspension has potential act smart working fluid, significantly enhancing numbers enclosed chambers. Research limitations/implications particle core (n-octadecane, phase-change material) shell (PMMA, encapsulation material). host fluid water particles considered form dilute suspension. Practical implications Using NEPCMs energy storage thermal systems show improving efficiency several engineering applications. merge beneficial characteristics PCMs enhanced conductivity nanoparticles, providing flexible alternative effective control. Originality/value explore water-type nanofluid boundary, uniformly heated cooled right boundary non-uniformly boundary.
