Abstract

A new flow control technique to improve the flow separation over flap by pulsed microblowing at the flow separated position is discussed in this paper. Firstly, the effect of various blowing parameters, including average blowing momentum and pulse frequency, are investigated in detail. Secondly, based on the comparison between the effects of continuous blowing and pulsed blowing, the mechanism of pulsed blowing flow control technique is also discussed. All of the tests have been conducted at low-speed wind tunnel with Reynolds number of 0.6×105-1.2×106 at flap deflection angle of δe=20° in Beijing University of Aeronautics and Astronautics.
