摘　　要：合成射流作为一种具有优越控制效果的主动流动控制技术,在提升飞行器气动性能、减振降噪、强化元器件散热等领域具有重要的学术意义和应用价值.经过30余年的研究,人们建立了更准确的合成射流数学模型,合成射流具有高卷吸能力的物理机理也得到不断深化.进一步优化合成射流激励器,提高控制效率成为了研究的重点.本文主要从激励器结构型式、激励器结构参数以及激励信号三个方面,总结了近年来在提高合成射流控制效果方面取得的研究进展,并对未来的研究重点进行了展望.As a significant active flow control method,the synthetic jet has been considered to be promising and of great potential in applications.Due to its superior control performance,synthetic jets have wide application in improving aerodynamic characteristics of aircrafts,suppressing vibration and noise,cooling electronic devices and etc.In recent years,a large number of synthetic jet models with higher accuracy have been proposed and the underlying mechanism of the efficient entrainment has been explored more vividly.The optimization of the synthetic jet actuator and further improving its controlling efficiency has attracted more and more attention.The optimization of the actuator and its application are summarized from three aspects respectively,i.e.,the actuator structure,the geometric parameters and the actuating signal.Moreover,the possible issues for future investigation have been suggested.
