Numerical Study on Vectoring Primary Flow with Adjacent Synthetic Jet with Dip Angle

Abstract

Based on the full flow field calculation model of the synthetic jet actuator-X-L model, numerical simulation is carried out on the influence of the main parameters of the directional control of the adjacent synthetic jet actuator, and the parameters of the actuators of different adjacent synthetic jets are analyzed. The amplitude, frequency, and phase difference of the device were analyzed. The results show that the larger the amplitude of the synthetic jet actuator, the more obvious the control effect of the synthetic jet on the main stream; the synthetic jet actuator has an optimal frequency, so that the main stream deflection efficiency is the highest, and the inclination angle lowers the optimal frequency, which reduces the requirement of the flow field control on the actuator frequency; the actuator phase difference makes the control efficiency adjustment width of the mainstream increase significantly, and there is an optimal phase difference, while right Side actuator phase advancement is more efficient than hysteresis control.
