摘要：

A numerical study was conducted to investigate synthetic jet-based boundary layer separation control in a serpentine inlet. Rectangular slots were chosen in this study, spanwise and streamwise orientations of these slots were discussed in detail. The results illustrate streamwise oriented synthetic jet has a higher resistance to the adverse pressure gradient. It penetrates deeper and exhibites stronger persistence than spanwise case as well. When jet momentum coefficient is equal to 1.62×10-3, and the characteristic frequency is 1, separation length is reduced by 38.39% relative to uncontrolled flow field. The performance of serpentime inlet using streamwise oriented synthetic jet are also superior to spanwise case. Outlet pressure coefficient is increased by 158.91%; total pressure recovery coefficient is increased by 0.71%, and total pressure distortion coefficient is reduced by 56.75%. ©, 2015, BUAA Press.
