A numerical model for hydrogen jets undergoing chemical reaction is developed on the basis of experimental findings. Basic equations for an axisymmetric and turbulent reacting gas flow are discretized by the applicaion of the second order explicit MacCormak method and the Flux-Corrected Transport smoothing technique. The turbulence is modeled by the k-epsilon two equations model. General patterns of the computed density distribution of the jet compare favorably with the corresponding experimental results deduced from Schliern photographs. The ignition time obtained from the rise in temperature and the amount of water production in the computation are generally consistent with those of hydrogen jet in the experiments., 資料番号: NALSP0008017, レポート番号: NAL SP-8}, title = {着火燃焼を伴う噴出水素流の数値解析}, year = {1987} }
