چکیده
The encapsulation technique of phase change materials in the nanodimension is an innovative approach to improve heat transfer capability and solve issues corrosion during melting process. This new type nanoparticle suspended base fluids call NEPCMs, nanoencapsulated materials. goal this work analyze impacts pertinent parameters on free convection entropy generation elliptical-shaped enclosure filled with NEPCMs by considering effect inclined magnetic field. To reach goal, governing equations (energy, momentum, mass conservation) are solved numerically CVFEM. Currently, overcome low problem material, NEPCM suspension used for industrial applications. Validation results shows that they acceptable. reveal values N u ave descend ascending Ha while id="M2"> gen has a maximum at id="M3"> Ha = 16 .

Investigation of Oriented Magnetic Field Effects on Entropy Generation in an Inclined Channel Filled with Ferrofluids
Dispersion of super-paramagnetic nanoparticles in nonmagnetic carrier fluids, known as ferrofluids, offers the advantages of tunable thermo-physical properties and eliminate the need for moving parts to induce flow. This study investigates ferrofluid flow characteristics in an inclined channel under inclined magnetic field and constant pressure gradient. The ferrofluid considered in this work i...
