In this paper, according to the work mechanism of SteamJet, With the certain small scaled turbojet for an influence, along flying trajectory calculating mass of import air and injection water, establishing the spray physics model/ mathematics model. Based on the equation of three-dimension Renault average N-S, air to adopt the limited physical volume method, the liquid adopts to the Lagrangian orbit model, with straight injecting the current method ,Simulate the field of air/ liquid two phase flow field to distribute of inlet to carry on mutually. The results indicate that spray have an effect on flow field configuration. It is concluded that the numerical model and CFD method for modeling spray flow processes in gas/liquid injector will be satisfactory. Similar to the SteamJet the United States puts forward, adopting water injection can satisfy to import the conditional request for pressure and temperature of compressor.
