Abstract
A synthetic jet is one of the methods of generating the jet and a synthetic jet actuator has been shown to be a useful tool for flow control. For the separation control, it is necessary to clarify the periodic behavior of the synthetic jet. In this study, the effect of excitation frequency on behavior of the longitudinal vortex in the case of the synthetic jet in a crossflow is investigated. Wind tunnel experiments are carried out using a hot-wire anemometry and the flow visualization technique was used to aid in understanding the vortical field. For f=60 Hz and 100 Hz, the synthetic jet promotes mixing and agitation in contrast to the f=200 Hz case. The longitudinal vortex generated by the interaction between a jet and a crossflow was not observed for f=200 Hz. The generation of the longitudinal vortex is affected by the synthetic jet frequency.
