The Effect of the Flow Characteristics and the Shape of the Blade-Cascade Passage on the Losses in the Peripheral Cross Sections of Gas Turbine Blades

The paper describes the results obtained from solving the Navier-Stokes equations in the course of an investigation of the structure of the flow and the level of the profile losses in the peripheral cross sections of turbine blades for Re = 2.0 x 10^5 to 1.2 x 10^6 the intensity of turbulence at the inlet e = 0.02 to 0.12, and the reduced velocity (lambdal(w2t) = 0.78.
