Heat transfer rat5s for laminar, convective heat transfer in the entrance region between parallel plates were investigated. A hydrodynamic solution was used in the solution of the energy equation in finite difference form on a digital computer. The thermal boundary conditions include constant heat input, constant wall temperature, one wall constant temperature and one wall insulated, and constant but different wall temperatures on the upper and lower walls. Approximate integral methods are shown to produce results that are in close agreement with the solutions in the present analysis for the constant heat input and constant wall temperature cases. The scope of the finite difference solution is limited to a narrow range of Prandtl numbers near unity, due to the small grid sizes required for convergence. Author
