Impingement heat and momentum transfer from a two-dimensional laminar jet

A numerical scheme is devised for predicting the flow field and subsequently the heat transfer of a laminar slot jet impinging on a flat surface. At nozzle exit, both parabolic and uniform velocity profiles are employed in the prediction of the flow field. Two thermal boundary conditions along the plate are investigated; namely uniform wall temperature and uniform wall heat flux. Numerical computations are presented for the friction coefficient and Nusselt number for various values of Reynolds number and nozzle to plate spacing. The present numerical predictions are in excellent agreement with the available experimental data, confirming the accuracy of the present numerical algorithm.
