Abstract

The relative effectiveness or blowing and suction in controlling separation and circulation is assessed in the present paper. This paper focuses on low momentum input from the leading and trailing edge regions and the effects of a sharp and round trolling edges. Blowing is most effective when it is applied near but upstream of the separation location for the narrowest slot possible. The effectiveness of suction improves when the slot is located near but downstream or the natural separation location and it is as wide as possible. The effects of adding trailing edge shapes on separation control were also explored. Most of the data presented was taken at incompressible speeds and at Re < 2.5*10^5.
