Effect of Unsteady Wake on Flow Control of the Low-Pressure High-Lift Cascade with Synthetic Jet

Abstract:

The flow separation is susceptible to appear and is known to affect the aerodynamic performance of the low-pressure high-lift cascade. Large Eddy Simulation was adopted in the present work and the periodic moving bar was employed to simulate the unsteady wake upstream of the blade. The flow control of the synthetic jet with unsteady wake was investigated in detail. The upstream wake increased the turbulent level of the boundary layer of the cascade. The synthetic jet got a better control under the effect of the upstream wake.
