• THE RATE OF HEAT TRANSFER COEFFICIENT AT THE LOWER AND UPPER WALLS

Abstract

This theoretical study of the rate of Heat transfer coefficient at the lower and upper walls have some practical applications to many diversified areas like geophysical flows, aero-space science, in particular aero-dynamic heating and in the problems of engineering applications such as MHD generators, Hall accelerators and in thermo-nuclear power reactors etc. The governing differential equations are solved analytically, using the prescribed boundary conditions in both phases and obtained exact solutions. Numerical calculations of the resulting solutions are performed and by varying the various physical parameters Hartmann number Ha, Hall parameter m, viscosity ratio , height ratio h, thermal conductivity ratio on the behavior of heat transfer when all the remaining governing parameters are held fixed.
