DIRECT ENERGY CONVERSION SYSTEMS. SUPPLEMENT 1. HEAT AND MASS TRANSFER FROM THE SURFACE OF A CYLINDER WITH DISCONTINUOUS BOUNDARY CONDITIONS TO AN INCOMPRESSIBLE LAMINAR FLOW.

Abstract

Heat and mass transfer studies for flow over a cylinder having a longitudinal-strip source of hear or mass, are presented. A theory for the two asymptotic cases of Pr6 approaches infinity and Pr approaches 0 is developed, giving the temperature profile and the transfer rate for such a strip. The theory includes the effect of the conductivity of the heating strip material. It is shown that if the conductivity of the strip material is very high, then the transfer rate is a measure of local wall shear-stress provided the Prandtl number of the convecting fluid is high. Experimental studies described include electrochemical mass-transfer studies carried out on a rotating cylindrical electrode carrier; and heat transfer studies carried out in an oil tunnel. Fair correlation between theory and experiment was found.
