The Experimental Investigation of Using Suction Surface Fences to Control Secondary Flow in Compressor Cascade

The effects of suction surface fences at different blade height on the cascade loss and secondary flow in compressor cascade were investigated through the detailed cascade exit flow field survey in low speed wind tunnel.The experimental results show that if the position of the suction surface fence can be properly selected,the secondary flow in the compressor cascade can be controlled effectively and the total cascade loss can also be reduced.
