Abstract

In this study, convective heat transfer in a magnetohydrodynamics flow over an immersed axi-symmetrical body with curved surface is investigated. The study is aimed at determining the velocity distribution, temperature variation within the thermal boundary layer of hydromagnetic fluid and the effect of heat generated within the boundary of an immersed axi-symmetrical body with curved surface. The magnetohydrodynamic flow in consideration is unsteady and the fluid is assumed to be of constant density. Convective heat transfer is caused by different temperature profiles which bring about temperature gradient. The temperature difference is due to the frictional forces on and within the surface of the body when fluid flows over it. The equations governing the flow over curved surfaces are highly non-linear and a suitable numerical method; finite difference method is used. This method is used because of its stability, convergence and consistency. A computer code is used to obtain results. The results are presented graphically and discussed. It was observed that when magnetic field parameter is increased there was a decrease in both velocity and temperature profiles. These results are applicable in designing devices requiring high maneuverability and low resistance to motion e.g. aerofoil and cooling fans.
