摘要：

MHD viscous electrically conducting fluid flow and heat transfer in a parallel plate channel partially filled with a porous medium and partially with a clear fluid was considered in the presence of an inclined magnetic field in a rotating system. Hall effects were taken into account. It was found that the Coriolis force, Hall current, and the permeability of the porous medium influenced significantly the flow behavior in the channel and the temperature field. Effects of the rotation parameter (R), Hall current parameter (m), permeability of the porous material (K), viscosities ratio parameter (φ1), Hartmann number (M), and angle of inclination (θ) of the applied magnetic field (H0) on the velocity distributions, temperature distributions, and the rate of heat transfer are depicted graphically and discussed. © TÜBİTAK.
