The blade pressure distribution of gas particle two phase flow in a compressor cascade has been investigated experimentally.Detailed measurements were made for three mass concentrations 1 1%

2 0% and 4 5%

and for two inlet velocities 10 and 22m/s

and for two inlet angles of attack 7° and 27 5°.The results for two inlet angles of attack 7° and 27 5° indicate that the solid phase has certain effect on the blade pressure distribution of the gas phase .With increasing inlet velocity and mass concentration

the effects of solid particles on the blade pressure distribution are enhanced and wake deviation is obvious.Also

the variation of the effects depends on the inlet angle of attack.
