MHD mixed convection of hybrid nanofluid in a wavy porous cavity employing local thermal non-equilibrium condition

Abstract The current study treats the magnetic field impacts on the mixed convection flow within an undulating cavity filled by hybrid nanofluids and porous media. The local thermal non-equilibrium condition below the implications of heat generation and thermal radiation is conducted. The corrugated...
