Influence of thermal boundary conditions on MHD natural convection in square enclosure using Cu–water nanofluid

Abstract

Numerical investigation for heat transfer with natural convection and nanofluid flow subjected to changeable thermal boundary conditions and inclined magnetic field has been performed. Effect of problem’s parameters on each other has been monitored. It has been reached to that inclination angle can justify the quasi-symmetric boundary conditions to be symmetric. In addition to that as inclination angle increases, the magnetic force pointed to horizontal trend; so the convection regime dominates the cavity. In a related context, nanoparticles provide conduction regime, increase and maintenance the rate of heat transfer all over the cavity. However thermal emission at ends of heat source–sink has been found to be constant when boundary conditions change in the pure case.
