In order to research the effects of the rim seal on the mainstream flow in a high-pressure turbine,the mainstream flow features of the original no-coolant gas ingestion and the four kinds of seal types for a turbine stage were compared.The analysis of computational grid independence and reliability validation for the numerical method was performed to guarantee the accuracy of the numerical calculation.The study shows that seal structure will reduce the efficiency of rotor and the stage power.The sealing flo...
