APPROXIMATE SOLUTIONS FOR SKIN FRICTION AND HEAT TRANSFER IN MHD CHANNEL FLOWS.

Abstract

The results are presented of a theoretical analysis of viscous and thermal boundary layer behavior on the electrically insulating wall of a rectangular MHD channel, using momentum and energy integral approximations. Steady, twodimensional, constant-property, low magnetic Reynolds number flow is assumed with magnetic and electric fields imposed parallel to the short and long channel side-walls respectively. Analytical and numerical solutions are obtained for laminar skin friction and heat flux, and for turbulent skin friction, as a function of distance from the channel entrance. These results are compared with those for the case of no applied fields and possible reasons for the differences are set forth. (Author)
