Abstract

This report documents the first manufacture and test of a single crystal (PMN-PT) piezoceramic diaphragm synthetic jet actuator for more efficient operation. The experimental investigation included laser vibrometry for diaphragm displacement measurement and hotwire anemometry for jet velocity measurement, as well as measurements of electrical power input to the disc. The performance of the single crystal device was compared with a synthetic jet actuator using a polycrystalline (PZT-5A) disc of the same geometry. For a fixed diaphragm drive voltage (20 V), the diaphragm displacement of PMN-PT is five times larger than PZT-5A. For comparable jet velocities (~40 m/s), the power conversion efficiency of the PMN-PT device is two times larger than the PZT-5A device. Finally, for comparable power conversion efficiencies (~20%), the peak jet velocity of the PMN-PT device is two times larger than the PZT-5A device.
