Abstract

PIV measurements have been undertaken to investigate the effects of varying orifice depth (h) and cavity height (H) on the vortex circulation of round synthetic jets in quiescent conditions. It is found that at the same stroke length, the normalized vortex circulation increases rapidly with a decreasing h when h/Do is less than 1. At h/Do equivalent to 0.5, a peak in the normalized circulation is observed suggesting that this is the optimum configuration in the current actuator design for maximum circulation production. An increase in cavity height is observed to increase the normalized vortex circulation. It is believed that Helmholtz resonance plays a role in this trend. The findings from this study provide useful information for optimizing the design of synthetic jet actuators.
