摘要：
The gas flow pattern, the local friction coefficients, the profile losses, and the outlet flow angles in a plane turbine cascade are modeled numerically using the 2-D Reynolds equations. For describing the turbulence characteristics, a two-parameter q-ω turbulence model is used. The flow pattern behind the cascade trailing edge is studied. The calculated values of the local gas pressure and the friction coefficient on the profile contour, the profile losses, and the outlet flow angles are compared with the experimental data for a transonic flow in a nozzle cascade at various reduced gas velocities behind the cascade and relative mass flows of the air ejected.
