  • With increase of the compressor loading,the blade surface boundary layer was easily separated but suppressed by unsteady upstream wake.In this paper,moving cylinder was used to produce unsteady wake,and different inlet wake angles were acquired by changing moving speed.This shows that the performance of stator will be improved on high blade loading while it varies little on low blade loading as the inlet wake angle increases.During the interaction of wake and boundary on high blade loading,increasing inlet wake angle will enhance the energy exchange between wake and boundary layer,which is a main factor to suppress the separated boundary layer and reduce the stator loss.
