AN APPROXIMATE METHOD FOR PREDICTING LAMINAR HEAT-TRANSFER BETWEEN PARALLEL PLATES HAVING EMBEDDED HEAT-SOURCES

An approximate method for. predicting the forced convection heat trans fer for flow between parallel plates having embedded, discrete hear so ul ces on one or both sides is presented. The spacing between sources is considered as adiabatic and the two-dimensional flow is laminar. Th e characteristics of such a flow can be described as flow in the isola ted plate, developing flow and fully developed flow regimes. The analy sis uses appropriate forms for the surface temperature and Nusselt num ber solutions for the flow regimes encountered Superposition is then a pplied to develop the discrete away solution for temperature and Nusse lt number regardless of the arbitrary and step nature of the boundary conditions. Comparisons to existing numerical solutions show good agre ement to within five percent of the predicted temperatures. A direct s imulation of an existing experimental result shows reasonable agreemen t in the Nusselt number solution. These results validate the methodolo gy for practical use including electronic cooling applications.
