| 摘 要： | 为研究自耦合射流与主射流空间布局对主流矢量偏转的影响,采用了二者平行布局的方式,利用压电陶瓷单缝自耦合射流作动器出口两侧的低压区的卷吸作用,使主射流发生了显著的矢量偏转。实验表明,主射流的偏转角与自耦合射流和主射流之间的间距d,高差s等参数有关。在实验条件下,自耦合射流使约5·4m/s流速的主射流产生了最大45°的矢量偏转。

| Abstract: | The interaction between a conventional rectangle primary jet and a synthetic jet was investigated experimentally.The synthetic jet actuator was parallel to the primary jet and the formation of a low-pressure region between the jets results in deflection of the primary jet towards the actuator jet. A detailed study shows that the vectoring angles vary with the distance between the synthetic jet and the primary jet. The experiment indicates that the 45°vector turning of 5.4 m/s primary jet is achieved by specially designed actuator while the maximum velocity value of the synthetic jet 5.5m/s is also achieved. |
