Numerical Investigation of High-Power Synthetic Jet Actuator Flowfield and Its Influence on Vectoring Control
Detailed two-dimensional unsteady numerical simulation is carried out to investigate a high-power synthetic jet actuator flow field and its design characteristic. Simultaneously, vectoring control of a primary jet and the dynamic mechanism are also studied. Firstly, the results show the actuator become more desirable as the rotating speed increases or the piston displacement enlarges with the invariable model and concerned parameters. Secondly, acting forces resulting from the synthetic jets have the push or pull effect on the primary jet and spanwise static pressure difference appears, which is the important reason for the variation of primary jet. Thirdly, with the given motor rotating speed, there is the maximal variation angle at certain velocity value of primary jet. Strictly speaking, the variation angle is the average value of variation angles at different center points of primary jet.
