Modelling of the bypass-transition in the linear turbine blade cascade
Original language description
This paper deals with modelling of the transitional flow in linear turbine blade cascade. The algebraic bypass-transition model based on the Narasimha equation for the intermittency coefficient which is implemented into the in-house numerical code is described. Proposed model is validated using test cases of the ERCOFTAC database (flow over flat plate without and with pressure gradient) and for flow in turbine blade cascade. The model was applied for calculation of flow in subsonic linear turbine bladecascade in a wide range of output Reynolds number. Results shows that an integral characteristics of the blade cascade (such as kinetic energy losses, total pressure losses, output Mach number) strongly depends on the development of the boundary layer.
