中文摘要：

采用商业软件ANSYS CFX针对将柯恩达效应应用于燃机涡轮的可行性进行了探索,得到了不同射流总压和射流口高度时的环量控制叶型涡轮叶栅的二维流场和气动性能。结果表明：环量控制涡轮叶栅在射流总压不太高的条件下,就能够达到并超过原型叶栅的性能水平,射流总压的变化直接影响叶栅性能;射流口高度对叶栅性能的影响主要体现在其对射流速度的影响,在射流口较小时比较明显。

英文摘要：

The idea of application of Coanda effect to gas turbine was proposed and studied in the paper.The performance of circulation control cascade under different jet total pressure and slot height was obtained through 2-D numerical simulation.The results show that the circulation control cascade can achieve the same performance level of the baseline turbine cascade under a moderate jet pressure.Jet pressure directly influences the cascade performance while the slot height takes effects especially when the height is small.
