Two-phase magnetohydrodynamic flow and heat transfer in an inclined channel

Abstract

Two-phase MHD flow and heat transfer in an inclined channel is investigated in which one phase being electrically conducting. The transport properties of both fluids are assumed constant. The resulting governing equations are coupled and nonlinear. An approximate solution is obtained using perturbation method. The results are presented for various values of the ratios of viscosities, thermal conductivities, heights of the fluid, Hartmann number, Grashof number and angle of inclination. It is found that the velocity and temperature can be. increased or decreased with suitable values of the ratios of viscosities, thermal conductivities, the heights and the angle of inclination. © 1997 Elsevier Science Ltd.
