Abstract:The improvement of the skin friction/heat transfer prediction theory of compressible turbulent boundary-layer combustion of hydrogen is conducted in this paper. The original theory is improved through two aspects. One is the modification of the relation between surface hydrogen mass fraction and Reynolds number by rebuilding the Kármán momentum integral relation. The other is the change of computational method of Prandtl number by adopting the molecular kinetic theory. The improved theory is used to make prediction of skin friction and heat transfer that are found to be better consistent with experimental results than original theory. In addition, a numerical experiment of boundary-layer combustion is conducted. By comparing the results given by numerical simulation and theoretical prediction, it also found that the improved theory shows better prediction performance than the original theory.
