外文摘要：A simplified model is proposed to predict the flow in a Steam Injector (SI)， based on the splitting in successive two phase flow processes。 SI experimentations have been carried out including pressure and void fraction measurements。 The results show that the model provides good values of flow rates and pressures inside the device and describes well its behavior 。 It will have to be enriched with dissipative processes， mainly friction in the mixing chamber and dissipation in the condensation shock in order to achieve the prediction of the outlet pressure that can reach more than 4 or 5 tunes the steam feeding pressure。
