Abstract

This study aims to examine the velocity and efficiency improvement of a synthetic jet actuator by utilizing a single-crystal piezoelectric disc. Laser vibrometer and hot-wire anemometry were used in the experiments to measure diaphragm displacement and output velocity, respectively. Experiments achieved a peak electro-fluidic power conversion efficiency of 43% with a peak output jet velocity of 114 m/s. A multi-physics computational simulation was developed to reproduce the experimental results. The simulation results showed an acceptable match with experimental data. Peak displacement and peak output jet velocity matched with 5% and 3% with experimental data, respectively.
