水下合成双射流流场特性与推力特性实验研究
Experimental investigation on characteristics of flow field and propulsion of dual synthetic jets in water
摘要
Abstract
The flow field and propulsion characteristics of dual synthetic jets (DSJ) in water is investigated using the particle image velocimetry (PIV) system and propulsion measuring system.The results of the experimental investigation reveal the noticeable symmetrical pattern of average flow field created by underwater dual sythetic jets actuator (DSJA).The influence of DSJA`s working parameters on flow field characteristics and propulsion of dual synthetic jets in water is studied by changing the driving frequency, amplitude of voltage and voltage waveform.The results shows that there is an optimum driving frequency existed, which generates the maximum propulsion, and the propulsion will increase according to the rise of the amplitude of voltage.关键词
