A numerical study on internal and external flow fields of synthetic jet actuator
The synthetic jet technology is a new active ow control method, which was through injecting small-scale perturbation into incoming ow at key points to realize ow control. In this paper, the actuator model was established, which integrates the fields of actuator chamber, actuator exit access and outer ow into one whole ow field. Then the formation and evolution of synthetic jet were simulated numerically by the finite volume method. The effects of actuation frequencies on ow velocities and distributions were discussed. It shows that jet velocities and jet evolutional distances as 300Hz of actuation frequency were better than other frequencies investigated in this paper. Furthermore, some computed results are obtained, which offer theory basis for synthetic jet technology applying in airfoil ow control of MAVS.
