摘要
推导出适用于带冷气喷射的涡轮叶栅内三维流动的控制方程，得出任意曲线坐标系下守恒型Ｎ—Ｓ方程和Ｅｕｌｅｒ方程的表达式。对熵的分析表明冷气与主流气体之间的焓差和速度差是冷气喷射引起熵变化的主要因素。
A type of governing equations is presented for the 3-D complicated flow in the turbine cascade with cooling-air injection. The derivation is performed for the concrete expression of N-S equations and Euler equations in the conservative form under the system of arbitrary curvilinear coordinates. With the analysis of entropy, it is shown that the differences of enthalpy and velocity between the cooling air and the mainstream gas are the main factors inducing entropy to vary.
