A plasma actuator has been widely studied as an active flow control device. We have developed a micro plasma actuator, which has small electrodes of 1 millimeter or less in size, for installing in small machinery. The wavy micro plasma actuator has induced streamwise vortices, enhancing the momentum mixing between mainstream and boundary layer. Additionally, we have developed the multistage type wavy micro plasma actuators so as to generate stronger streamwise vortices than those induced by single one. For evaluating the effect on separation control, we have performed PIV measurement of flow around NACA0012 airfoil at low Reynolds number. PIV results have presented that both micro plasma actuators have suppressed separation region.
