MAGNETOHYDRODYNAMIC HEAT-TRANSFER IN 2 PHASE FLOW

Abstract

The problem of two-phase magnetohydrodynamic flow and heat transfer in a horizontal channel is investigated analytically. The fluids in the two phases are assumed to be immiscible, incompressible, electrically conducting. Further the two fluids are assumed to have different viscosities, thermal and electrical conductivities. The transport properties of the two fluids were taken to be constant and the bounding plates are maintained at constant and equal temperature. The analytical solutions for velocity and temperature distributions are obtained and are computed numerically for different values of parameters. The results are presented graphically. It is found that in case of open circuit problem for negative values of the electric load parameter Re, the effect of increasing the Hartmann number M is to accelerate the velocity and to increase the temperature field in contrast to the short circuit case. It is also found that with suitable values of the ratios of depths, viscosities, thermal and electrical conductivities, the velocity and temperature can be increased.
