Nizam Dahalan, supervisor Mechanical engineering Also available in printed version Synthetic jet actuator is an active flow control device that used to delay the flow separation and improves the aerodynamic performance such as the wing of an aircraft. The objective of this study is to investigate the performance of synthetic jet actuator design for flow separation with the effect of various orifice depth, cavity thickness and the number of piezoelectric diaphragms using experimental method. There are seven models of synthetic jet actuators were designed, fabricated and testing. Three of the models have different orifice depth and four models built up with various cavity thickness. The experiments were conducted by single and dual piezoelectric diaphragms. A hot-wire anemometer is used to determine the exit air jet velocity through the orifice. The main outcomes of the experiments are to identify the maximum exit air jet velocity and turbulence intensities on different applied frequencies for both single and dual diaphragms. The results show that the exit air jet velocity increases better if the orifice depth reduced and the cavity thickness is smaller. And the best performance of the synthetic jet actuator is identified on the piezoelectric dual diaphragms. shafika UTM 125 p.
