On the Governing Equations for 3-D Flow Field in the Cascade with Cooling-air Injection

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.
