Abstract
A numerical treatment of the interaction between two models of heat transfer, namely, surface thermal radiation and natural convection, of micropolar loaded with Al2O3 and Cu nanoparticles within a porous cavity in the presence of MHD of inclination J with entropy analysis is presented. Both 1st and 2nd laws of thermodynamic are applied to analyze the problem. The 2-D steady-state flow governing equations have been resolved via Alternating Direction Implicit (ADI) based on the concept of the finite volume method. The exhibited physical factors are the heat source length 0.2 <= B <= 0.8, the heat generation/absorption -2 <= Q <= 2, the radiation factor 0 <= R-d <= 1.0, the vortex viscosity parameter 0 <= k <= 2, Hartmann number 0 <= Ha <= 100, the inclination angle 0 <= Phi <= pi and and the alumina-copper volume fraction 1% <= phi(Al), phi(Cu) <= 5%. The presented computations are portrayed graphically. The outcomes illustrate that the average Nusselt number weakens with larger values of vortex parameter k whereas strengthens due to total solid volume fraction phi(phi(Al) + phi(Cu)). In addition, R-d leads to strengthen the global entropy generation.
