Abstract

In this paper heat transfer of MHD fully developed incompressible cowling flow at thermal entrance region of a flat duct under constant heat flux at walls is investigated by finite difference technique. The flow is in X-direction and applied magnetic field in the y-direction. The flow pattern is determined for different values of Hartmann number (m), heat generation ( ) parameter and Electric field factor (e). Comparisons have been made with ordinary fluid flow and MHD flows. It is observed at MHD has effect of increasing temperature in cowlings flow. The variation of the wall temperatures for different values of M, e, are shown graphically. Pseudo local Nusselt number variations shown graphically.
