Convective MHD flow of hybrid-nanofluid within an elliptic porous enclosure

The essential aim of this modeling is to scrutinize the irreversibility and heat transfer of hybrid nanomaterial within a permeable medium. The inner elliptic surface experiences the uniform flux and outer wall maintains cold temperature. To scrutinize the impact of porous region, difference between the temperature of fluid and solid matrix was involved and stream function formulation was applied to simplify the equations. Outputs were obtained by means of CVFEM and its accuracy was check by comparing with previous article. Greater values for Ψ can be obtained with rise of Ra while opposite tendency appears for Ha. When Nhs* = 1, Ha = 1, growth of Ra provides 3.86 times lower values of Nu. Nu declines about 70.1% with growth of Ha when Ra* = 5, Nhs* = 0.01. Unfavorable effect of MHD on Nu declines with augment of Nhs*. Nu reduces about 72.5% with augment of Nhs when Ra* = 5, Ha = 1.
