Impact of magnetic field on convective flow of a micropolar fluid with two parallel heat sources

A numerical study is performed to analyze the buoyancy convection induced by the combinedeffect of temperature and species gradients inside an inclined square cavity. The two side walls of the cavity are maintained at a constant temperature. A uniformly thin heated plate is placed at the center of the cavity. The horizontal top and bottom walls are adiabatic. Numerical solutions of governing equations are obtained using the finite volume method coupled with the upwind and central difference technique. Numerical results of the two-dimensional flow field governed by the Navier-Stokes equations are obtained over a wide range of physical parameters, namely the Rayleigh number, the Hartma number, the inclined angle of the magnetic parameter and vortex viscosity parameter. It is observed from the results, the heat transfer rate is reduced when increasing Hartma number, inclination angle and vortex viscosity parameter. The higher heat transfer rate is obtained based on the Newtonian fluid as compared to the micropolar fluid.
