Abstract

Active flow control (AFC) as a method of separation control was investigated for laminar flow over a curved wall. Experimental research has demonstrated that AFC using periodic suction and blowing is an extremely efficient way to suppress or weaken separation. However, there is a lack of accurate computational data for this flow. We applied CFD to investigate the experimental geometry of Seifert and Pack (1999), which consists of the top surface of an airfoil mounted on the side wall of the 0.3-meter cryogenic wind tunnel at NASA Langley Research Center. We used an high order finite-difference code to simulate laminar flow at a Reynolds number of Rec = 104 and Mach numbers of 0.25 and 0.65. The effects of forcing frequency and amplitude were investigated, as well as effects of compressibility.
