In this paper, two kinds of former computing method for ejector design-classical thermodynamics and gas aerodynamic were discussed and analysed objectively on their calculation results and shortcomings. On the basis of that, a new numberical method in accordance with the properties of medium and basic thermodynamical theory was proposed so that it would be able to adapt better the requirement of designing ejector with high speed two phase flow. Three calculations in the same working state were completed with the test each other. The physical and mathematical modle of new numberical method was introduced in details.
