The flow in turbomachinery is strongly influenced by the rotor-stator interactions. It is known that the unsteadiness of the flow has for effect to advance the laminar-turbulent transition and to alter the heat transfer. The problem of the wake-boundary layer interaction has been studied experimentally by using a simplified geometrical configuration. The stator blade is simulated by a flat plate on which the development of the boundary layer disturbed by periodic wakes is observed. The wakes are generated by moving bars having a circular section, put upstream of the flat plate and running with a constant velocity in the wind of a low-speed tunnel. Numerical studies relating to the phenomenon of interaction are limited. Part of the experimental study has been carried out in a fully turbulent flow in order to avoid the problem of transition. These results are compared with those from a code solving the fully turbulent unsteady boundary layer equations. |
