In this study, the incorporation of a flexible baffle structure at base microelectronic channel is examined to determine its impact on thermal and fluid dynamics. The investigation covers two configurations: case 1, where heat source situated top section microchannel, 2, with placed bottom. To cool electronic component, nanofluid consisting water aluminum oxide (Al2O3) nanoparticles, in concentrations varying from 0% 6%, injected into exhibiting periodic velocity profile inlet. governing...
The lid-driven top wall's influence combined with the side walls' waviness map induce mixed convection heat transfer, flow behavior, and entropy generation of a hybrid nanofluid (Fe3O4-MWCNT/water), process analyzed through present study. working fluid occupies permeable cubic chamber is subjected to magnetic field. governing equations are solved by employing GFEM method. results show that force significantly affects fluid's thermal where force's perpendicular direction remarkably improves...

This article discusses the heat transfer characteristics of mixed convection NEPCM-fluid (Polyurethane/ Nonadecane dispersed in water) contained within a wavy-sided walls cavity. Mixed is caused by an adiabatic rotating cylinder located cavity center, while natural results from deferential heating side walls. The upper and lower are insulated. Galerkin finite element method (GFEM) implemented COMSOL CFD package employed to solve governing equations. influence nanoparticles volume fraction (Ø...
In this numerical study, a cubic box filled with Nanoparticle Enhanced Phase Change Material (NEPCM) (mixture "N-Octadecane/alumina (Al2O3)"), is considered. Using Comsol-Multiphysics program, the configuration treated as 3D symmetric simulation problem under fixed boundary conditions. Besides, heat transfer fluid (HTF) generates non-uniform temperature that varies linearly along an internal tube installed in lowest area of enclosure to ensure melting NEPCM. Therefore, purpose study...
