Influence of ingested gas crossflow on the formation and structure of secondary flows in the blade passage of a gas turbine

  • K. N. Volkov

This paper considers the influence of the mass flow of the gas ingested from the cavity formed by the rotor-to-stator clearance on the formation and structure of secondary flows in the blade passage of the gas-turbine stage. The flow is described by the Reynolds-averaged Navier-Stokes equations, to close which the Spalart-Allmaras model and the k-ε model of turbulence with corrections for the rotation and curvature of the streamlines are used. Comparison of the results of the numerical simulation obtained from the point of view of different turbulence models is made.
