| Popis: |
The boundary layer transition process on compressor blades in a multi-row environment is mainly influenced by incoming periodic wakes generated by the upstream blade row. To simulate such conditions experimentally, a moving bar wake generator device was used which is arranged in front of a compressor cascade in a high speed wind tunnel. A Hot-Film-Array measuring technique was used to investigate the transition process on compressor blades with unsteady inlet flow conditions. This paper discusses some aspects of unsteady transition on the suction side of the compressor blades. The structure of the wake and in particular its turbulence intensity distribution is shown to cause different kinds of multi-mode transition. |
