| Abstract: | A micro piezoelectric synthetic jet actuator with side nozzle is designed,and the momentum coefficient is selected as an important design parameter of synthetic jet actuator.The jet velocity of different structure sizes of nozzle were calculated,and the nozzle width influence on momentum coefficient was analyzed.Based on these,the optimal size range of the nozzle were determined.The numerical simulation results of NACA0015 airfoil with 23° attack angle showed that the micro piezoelectric synthetic jet suppress flow separation of the boundary layer effectively.The fabrication process of this kind of actuator was proposed,and the prototype device was obtained. |
