高效合成射流激励器研究进展及展望

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.
