Abstract

The steady Couette flow with heat transfer of a conducting fluid is studied, taking into consideration the Hall effect. The viscosity of the fluid is assumed to vary with temperature. The fluid is subjected to a constant pressure gradient and an external uniform magnetic field perpendicular to the plates. which are kept at different but constant temperatures. The effect of Hall's current on the velocity components as well as on the temperature, is more pronounced for higher values of viscosity exponent. It was also found that the Hall term has a marked effect on the axial and transverse components of the skin friction and the Nusselt number at both walls of the channel.
