Flow control method using ejection in a turbine flow

A turbine flow control technique using air ejection near blade trailing edge to achieve Superior aerodynamic performance is proved numerically by CFD simulation. The advantages of air ejection near blade include high lift and low loss on the suction side of blade. The result shows that, the control method is effective for reduced the separation region, improve the distribution of pressure over the blade. Within the certain range of data, reduce the conclusion of total-pressure recovery coefficient and total pressure loss coefficient.
