Abstract

Computational Fluid Dynamics (CFD) technique was adopted to investigate the shape effect synthetic jet actuators. Three different pulsation frequencies of 280Hz, 560Hz and 1120Hz at oscillating amplitudes of 80μm, 40μm and 20μm, respectively were performed. The doubling frequency with halved oscillating amplitude allowed theinvestigation to be carried out with fixed jet velocity over a cycle. The shape effect was investigated by varying aspect ratios of the synthetic jet actuator while fixing the cavity volume. Aspect ratio of 0.5, 1, and 2 were conducted where they represented a tall, square, and rectangular cavity. A sinusoidal fashion of the oscillatingdiagram was applied so that the synthetic jet actuator switched between expulsion and ingestion phases periodically. The generated vortices and jet flow were examined in detail in this paper. The cavity dimension affected the flowstructure and through investigation a relationship between cavity height and width versus vorticity was established.
