NON-NEWTONIAN NATURAL CONVECTION IN A SQUARE BOX SUBMITTED TO HORIZONTAL HEAT FLUX AND MAGNETIC FIELD

ABSTRACT
The current work numerically investigates free convection in a square box filled with a non-Newtonian conductive fluid, which is numerically analyzed and is subjected to a steady heat flux at the normal walls, while the horizontal walls are thought of as adiabatic. To examine the impacts of the regulating parameters, including Rayleigh number, behavior index, n, and Hartmann number, on fluid-flow and heat transfer, the governing equations are solved numerically by applying the finite volume method. The results are shown and analyzed in terms of streamlines, isotherms, flow intensity, medium Nusselt, and velocity profiles.
