【Abstract】 This paper presented a theoretical research on the flow and heat transfer of laminar liquid film over a vertical plate of constant wall temperature. Solving the integral equations of hydrodynamic and thermal boundary layer, the flow and heat transfer characteristics in the developing region were obtained, and the effect of initial flow state and the Prantl number on heat transfer were also discussed.更多还原
