HEAT TRANSFER TO AN ELECTRICALLY CONDUCTING FLUID FLOWING IN A CHANNEL WITH A TRANSVERSE MAGNETIC FIELD
Abstract
An nalysis is made for forced-convection heat transfer to laminar flow of an incompressible electrically conducting fluid between parallel plates. The plates are heated (or cooled) with a uniform wall heat flux, and internal heating within the fluid is present from viscous and electrical dissipations. The fluid enters the heated section of the channel with a uniform temperature, and the velocity distribution within the heated section is assumed to be fully developed. A magnetic field is imposed perpendicular to the channel walls, and there can be a net electric current flow parallel to the walls and perpendicular to the flow direction. The results give the wall temperatures that will be present for various magnetic fields and electric current flows and the duct length required to obtain a fully developed temperature distribution in the fluid.
