Radiative and heat generation effects on MHD mixed convection of non-Newtonian nanofluids in lid-driven inclined odd-shaped porous cavity containing obstacle using local thermal non-equilibrium condition

The present work examines the local thermal non-equilibrium condition (LTNEM) on the mixed convection of non-Newtonian nanofluids in a lid-driven inclined odd-shaped porous cavity involving obstacles. The SIMPLE algorithm in the finite volume method (FVM) is adopted to handle the present physical problem. The impacts of pertinent physical parameters such as length/location of heaters, thermal radiation, heat generation parameter, Hartmann number, and microrotation parameter on the streamlines, isotherms of a fluid, isotherms of a solid, and iso-microrotations as well as the local Nusselt number, and average Nusselt number are investigated. The major achieved numerical results indicated the importance of the heater length B and location D on the improvement of the heat transport in fluid/solid phases within an odd-shaped cavity. Expanding B enhances the values of local Nusselt number in a fluid phase Nufs and lowers the values of the mean Nusselt number Numf. The heat generation parameter Q improves the isotherms, Nufs, and Numf. The thermal radiation parameter Rd acting effectively in enhancing isotherms of a solid phase and local Nusselt number in a solid phase Nuss.
