| 摘 要： | 设计了合成射流激励器及实验测试系统。对两大小不同激励器工作于不同驱动频率及激励电源电压幅值分别进行了实验，并对激励器出口速度进行了分析。实验测得的合成射流出口最大峰值速度可达5m／s，驱动频率对激励器出口射流速度影响直接明显，且合成射流激励器有工作频谱范围限制。通过频谱分析显示，只有最大峰值频率与激励频率相等或接近，而且各峰值频率与最大峰值频率成倍频关系时，合成射流激励器将电能转化为合成射流动能的效率才能达到较高。

| Abstract: | Designed the actuators and the experimental system.Two synthetic jet actuators on the condition of the different driving frequency and voltage were tested.The flow velocity above the actuator exit was analyzed.The maximum flow velocity above the actuator exit can arrive to 5m/s.The forcing frequency influences the synthetic jet velocities above the actuator exit directly and apparently.And the synthetic jet actuator has a working band spectrum limited.Based on analyzing the power spectra,just the maximum peak value frequency is near to the driving frequency and the other peak value frequencies are times of the maximum peak value frequency,then the synthetic jet actuator working efficiency is high. |
