[Abstract]:Active flow control technology has always been the frontier and hot spot of hydrodynamics research. In order to solve the problems of poor adaptability and low energy efficiency of conventional synthetic jet flow control, the synthetic double jet and its flow control technology are developed. In this paper, the main research progress is reviewed. The basic idea of the design of synthetic jet actuator based on the principle of comprehensive utilization of energy and the principle of gas pressurization is proposed. The synthetic double jet, the vector synthesis double jet, the synthetic double jet base continuous jet, the synthetic heat / cold jet are invented. A series of self-sustained synthetic double jets and a new type of synthetic jet actuator. The dual jet actuator solves the environmental adaptability problem caused by ballast failure, and has the characteristics of energy efficiency, controllable frequency multiplication and unique vector function. The application directions of synthetic double jet separation flow control, vector control, supersonic / hypersonic inlet flow field control, aerodynamic heat control, heat dissipation cooling, anti-ice removal, underwater bionic propulsion, etc have been carried out. The new functions of double jet control efficiency multiplication and application in extreme environments are verified.
