Modeling approach for nanomaterial convective migration with inclusion of Lorentz force

Abstract

Hybrid nanomaterial migration through a permeable container has been simulated in current article with considering buoyancy effect. The inner surface absorbs constant heat flux and horizontal magnetohydrodynamic (MHD) is imposed. To employ the role of new fluid, homogeneous approach formulation was applied definition of stream function creates simpler form of equations. CVFEM was incorporated to model the equations. Entropy generations owing to various factors were examined with reporting contour plots. Variations of Be and Nu were reported by using 3D plots. Growing Ra, power of eddy rises and circular wall temperature decreases about 40%. Besides, Nu augments about 129.8% with growth of Ra while Be declines about 70.8%. As permeability augments, Nu enhances by 11.01% but Be decreases about 8.36%. Existence of Lorentz force make the hybrid nanofluid to move with lower velocity and Nu reduces about 24.5% while Be augments with impose of greater magnetic force.
