Abstract
A synthetic jet is promising technique to promote mixing and to control flow separation because it introduces flow perturbation without a net mass injection and can downsize the device. The purpose of this study is to investigate the three-dimensional flow behavior and the possibility on the interaction of the synthetic jet with cross flow in low Reynolds number using scanning stereo-PIV. Continuous jet with the same parameter is prepared to compare with the synthetic jet. A pair of longitudinal vortex is observed in both jets. The maximum vorticity of Synthetic Jet in cross flow (SJCF) remains higher than Continuous Jet in cross flow (JICF) at downstreem, although the vorticity of SJCF is similar to JICF near the orifice.
