Abstract:

The flow visualization by means of smoke and measurement of 3 -D flow field are conducted to investigate physical model of the streamwise corner vortexes in a compressor cascade.The exoerimental results describe not only the flow pattern and structural characteristics,but also the iateraction of the corner vortexes with the blade surface boundary layers in the cascade.Based on this physical model, the mechanism has been discussed that high losses are caused by the corner vortexes.

Key words: compressor .cascades, earner flow
