设计了一种卧式合成双射流激励器(DSJA),并对其在翼展中段控制NACA0015翼型大攻角流动完全分离进行试验研究,分析了合成双射流激励器两射流出口位置及射流能量对控制机翼流动分离的影响规律。结果表明:合成双射流激励器对机翼大攻角流动分离具有很强的控制能力,可显著提高机翼流动分离攻角;合成双射流激励器两射流出口相对分离点的位置是影响控制效果的重要参数;合成双射流激励器两出口任一出口位于分离点之前,且越靠近分离点,其对边界层分离的控制效果越好,并且当分离点位于合成双射流激励器两出口之间,且离第一出口位置较近时,合成双射流"接力"控制机翼分离的效果更加明显;与合成射流"单射流"相比,合成双射流"两射流"对分离点位置的有效控制区域明显增大。此外,提高合成双射流激励器的射流能量,其控制机翼流动分离的能力提高。

A horizontal dual synthetic jet actuator(DSJA) is designed. And experimental investigation on the separation flow control of stalled NACA0015 airfoil at high angle of attack is carried out with dual synthetic jet actuator. Characteristics of the flow separation control under DSJA with different jet locations and different jet energy are investigated. Results indicate that the stall angle is delayed by introducing DSJA. Jet locations of DSJA play a critical role. It is interesting that the control efficiency will be excellent when any of the dual synthetic jets locates in front of and is close to the unexcited separation point. When the separation points are between two exports of DSJA and the first export is close to the separation point, the effect will be better for DSJA to control airfoil separation. It suggests the DSJA has stronger ability than the synthetic jet actuator controlling flow separation. What's more, the ability of dual synthetic jets control flow separation can be increased by increasing jet energy.
