VARIABLE CONDUCTIVITY FULLY DEVELOPED MHD CHANNEL FLOW,

Abstract

Fully developed MHD channel flow was studied for several conductivity profiles to determine the effect of non-uniform electrical conductivity on the flow variables. The velocity profiles, volume rate of flow, and shear at the wall were investigated. If the conductivity only varies near the wall, the flow is moderately affected. If the conductivity in the central portion of the channel varies, significant changes (as much as 300% error based on uniform conductivity results) can occur. Variable conductivity has its greatest effect when the conductivity increases from the centerline to the walls. Inflection points can occur in the velocity profiles when the conductivity decreases from the centerline to the walls. (Author)
