2-PHASE MAGNETOHYDRODYNAMIC FLOW AND HEAT-TRANSFER IN AN INCLINED CHANNEL

Two-phase MHD flow and heat transfer in an inclined channel is investi gated in which one phase being electrically conducting. The transport properties of both fluids are assumed constant. The resulting governin g equations are coupled and nonlinear. An approximate solution is obta ined using perturbation method. The results are presented for various values of the ratios of viscosities, thermal conductivities, heights o f the fluid, Hartmann number. Grashof number and angle of inclination. It is found that the velocity and temperature can be increased or dec reased with suitable values of the ratios of viscosities, thermal cond uctivities, the heights and the angle of inclination.
