Abstract
The paper considers the analysis of the secondary flow intensity and pattern in a rotating channel which simulates a cooling channel of the rotating blade of the gas turbine engine. As a basic variant, a circle cross-section channel with the diameter of 6 mm and the length of 80 mm was chosen. The calculations of the air flow structure in the rotating channel in various geometric and operation conditions were carried out, which allowed assessing the influence of air pressure, temperature and air flow on the secondary flow intensity. The calculations were performed by solving the Reynolds-averaged Navier-Stokes equations (the RANS method) using the SST (Shear Stress Transport) turbulence model. The numerical grids were tetrahedron. The air ideal gas was used as the working medium.
