Numerical simulation for entropy generation and hydrothermal performance of nanomaterial inside a porous cavity using Fe3O4 nanoparticles

Computational analysis of exergy loss of laminar nanomaterial flow by including magnetic effect has been implemented in current research. CVFEM was incorporated to solve the describing equations. The influences of Darcy, Hartmann numbers as well as buoyancy impact on irreversibility have been explored. Lower temperature of walls occurs with higher Rayleigh number. Stronger magnetic field produces resistance to nanofluid transportation which reduces the Nusselt number. Boundary layer reconstructs more with augment of Darcy number
