• EFFECTS OF A MAGNETIC FIELD ON THE FREE CONVECTIVE FLOW OF JEFFREY FLUID PAST AN INFINITE VERTICAL POROUS PLATE WITH CONSTANT HEAT FLUX

Abstract

The study of flow and heat transfer for an electrically conducting fluid past a porous plate under has attracted the interest of many investigators in view of its applications in many engineering problems such as magnetohydrodyanmic (MHD) generator, plasma studies, nuclear reactors, oil exploration, geothermal energy extractions and the boundary layer control in the field of aerodynamics. The Jeffrey model is relatively simpler linear model using time derivatives instead of convected derivatives, for example the Oldroyd-B model does, it represents a rheology different from the Newtonian. Yamamoto and Yoshida (1974) have studied the flow of a viscous fluid past an infinite vertical porous plate with convective acceleration. An exact solution for the flow of a non-Newtonian fluid past an infinite porous plate was studied by Rajagopal and Gupta (1984). Ogulu and Amos (2005) have investigated the free convective flow of a non-Newtonian fluid past a vertical porous plate.
