设计加工了单膜双腔式斜出口合成射流激励器,应用PSI DTC Initium压力扫描系统对斜出口合成射流激励器在S进气道主动流动控制中的应用进行了研究。结果表明:斜出口合成射流激励器能够抑制S进气道分离流动,提高出口总压恢复系数σ和降低畸变指数DC90,只需通过改变激励器的工作电压和频率,就可实现对S进气道内部流场的控制。在共振频率下,当来流速度V=80m/s,采用斜出口合成射流控制可使出口截面平均总压恢复系数增加0.37%,此时所耗合成射流能量仅为主流的0.24%。
The single-film double-chamber inclined jet synthetic jet actuator was designed and processed. The application of the inclined jet synthetic jet actuator in S-inlet active flow control was studied by PSI DTC Initium pressure scanning system. The results show that the synthetic jet actuator with oblique outlet can suppress the flow of S inlet and outlet, increase the outlet total pressure recovery coefficient σ and reduce the distortion index DC90. Only by changing the operating voltage and frequency of the actuator, Road internal flow field control. Under the resonant frequency, when the flow velocity is V = 80m / s, the average total pressure recovery coefficient of the outlet cross section can be increased by 0.37% with the jet control of the inclined outlet. At this time, the energy consumed by the synthetic jet is only 0.24% of the mainstream.
