Abstract
Laminar natural convection in vertical channels has received considerable attention in the literature, principally because of its value as a simplified mathematical model for electronics cooling. Bar-Cohen and Rohsenow (BC and R) applied the correlation technique for Churchill and Usagi nto obtain predictions for heat transfer in the vertical channel configuration. The correlating equations obtained in BC and R gave favorable comparison with previous experimental data and numerical solutions. The symmetric uniform wall heat flux case from is considered in the present note. Maximum channel wall temperature rise, as predicted from the correlating equation, is expressed in terms of dimensional variables. This gives an alternate representation of results for design purposes.
