Özet

The problem of steady laminar magnetohydrodynamic (MHD) mixed convection heat transfer about a vertical slender cylinder is studied numerically A uniform magnetic field is applied perpendicular to the cylinder The resulting governing equations are transformed into the non-similar boundary layer equations and solved using the Keller box method The velocity and temperature profiles as well as the local skin friction and the local heat transfer parameters are determined for different values of the governing parameters mainly the transverse curvature parameter the magnetic parameter the electric field parameter and the Richardson number For some specific values of the governing parameters the results agree very well with those available in the literature Generally it is determined that the local skin friction coefficient and the local heat transfer coefficient increase increasing the Richardson number R(1) (i e the mixed convection parameter) electric field parameter E(1) and magnetic parameter Mn (C) 2010 Elsevier B V All rights reserved
