Abstract

Loads and shear stress measurements, as well as PIV flow field visualization, of a high lift wing-body half model using jets/synthetic jets flow control methods are conducted in a low speed wind tunnel. Results show that the maximum lift coefficient of the taking-off/landing configuration can be increased by 40.8%, and the stall angle of attack can be increased by 4.34° with jets flow control devices on wing; while the maximum lift coefficient can be increased by 19.0% with jets flow control devices on flap, and 0.87% with synthetic jets on flap. Flow control with the energy cost goes the similar way, which means that the flap synthetic jets flow control costs least. The shear stress is increased with the separation effectively controlled, accordingly the lift coefficient is increased.
