Article Description

The current study concerns with the mixed convection process of Casson hybrid nanofluids within split lid-driven porous inclined triangular enclosures with elliptic obstacles. The top wall of triangular containers is split to two-parts; those move to left and right directions and four cases are considered based on the direction of the movements. The inner elliptic shape has various thermal conditions, namely, hot, cold and adiabatic. An inclined magnetic field and a heat generating porous medium are considered. The considered non-Newtonian hybrid nanofluids are methano-Ti6Al4V + AA7075, ethylene glycol-Ti6Al4V + AA7075 and engine oil- Ti6Al4V + AA7075. Comprehensive analyses for the heat transfer at the top moving and the inner elliptic boundaries as well as the entropy generation are performed. FEM-CBS algorithm is applied to solve the governing system. The major findings revealed that the cases of UL=-1,UR=1 and cold ellipse give the highest rate of the heat transfer. Also, engine oil- Ti6Al4V + AA7075 augments the Nusselt number more than the other types of the non-Newtonian hybrid nanofluids. Furthermore, using methanol as a based hybrid nanofluids is a better for obtaining the higher irreversibility rate.
