摘　　要：采用分区网格技术，以Ｅｕｌｅｒ方程为主控方程，数值模拟了民用飞机的动力发动机内外流场。A simulation method has been developed for the analysis of powered engines, whose components include the outer cowl, spinner, fan face, fan exit plane, and core cowl geometry. In the simulation, either the mass flux or the static pressure can be prescribed at the fan face. The total pressure, total temperature, flow direction and the bypass ratio are specified at the turbine or fan exit plane, and the exhaust plume emerges naturally as part of the global solution. Comparison of numerical results with test data shows a very good agreement.
