Lorentz force impact on hybrid nanofluid within a porous tank including entropy generation

摘要

Computational analysis was performed to scrutinize the MHD hybrid nanofluid free convection with combination of entropy generation within a permeable tank. Flow pattern was reported for wide range of scrutinized parameters. Outputs reveal that convective flow intensity augments with rise of permeability and stronger thermal plume generates. Isotherms reveal that growth of Lorentz force leads to less intensive heating and isotherm with less distortion appears. Insertion of magnetic field makes weaker convective flow and lower temperature gradient. As temperature of heat source reduces with rise of Hartmann number, Nu_(ave) decreases and greater exergy loss occurs. Lower surface temperature is achieved with rise of permeability of zone which is led to greater Nu_(ave).
