Numerical Modelling of Transonic Flows in Wind Tunnel Test Section
Original language description
The paper deals with numerical simulations of transonic flows through various turbine cascades in a confined channel corresponding to boundaries of real wind tunnel. The boundaries of the wind tunnel are impermeable or there can be permeable tailboards to diminish shock wave reflections. The mathematical model is based on Favre-averaged Navier-Stokes equations closed by a turbulence model and model of transition to turbulence. The mathematical model is solved by an implicit finite volume method with multi-block grids. Several types of rotor rows in the last stage of low pressure cylinder are presented, with subsonic or supersonic inlet. The results are compared with optical measurements and simulations of periodic cascades. The validity of experimental reference flow parameters in relation to computed flow patterns is discussed.
