Abstract
Separated flow can be effectively controlled through the management of blade boundary layer development. Numerical simulations on a highly-loaded, low-solidity compressor cascade indicate that combined blowing and suction flow control technique can significantly improve cascade performance, especially in increasing the cascade loading and static pressure ratio as well as decreasing the loss coefficient. Meanwhile, it is more effective to improve cascade performance by blowing near leading edge on suction surface than suction near trailing edge. Both the locations and flow rates of blowing and suction are major impact factors of this method to cascade performance. Comparing to the baseline, the static pressure ratio increases by 15% and loss coefficient decreases by 80%, with a blowing fraction of 1.7% and a suction fraction of 1.38% of the inlet mass flow.
