【摘要】：提出一种补气式等离子体射流(ASPSJ)发生器,在常规火花放电式等离子体射流(PSJ)发生器腔体上连接单向阀,改善发生器吸气复原阶段的补气量和射流的连续性,以获得能量更高的合成射流。研究了在不同加载电参数下,不同类型单向阀对发生器最大射流速度的优化作用;通过正交实验法确定了补气式等离子体射流发生器的最佳工作电参数,以获得最高的合成射流速度。文中的等离子体射流发生器配以所选择的补气单向阀,最优加载电压频率为150 Hz,幅值为50kV,占空比为15%。实验结果表明,补气式等离子体射流发生器将最大射流速度提升20%以上,高射流速度的工作频带由单点扩展到100Hz,以期在应用于流动控制时获得更好的效果。研究成果为后续的主动流动控制的应用研究提供了指导。
[Abstract]:An air supply plasma jet (ASPSJ) generator is proposed, which is connected with a one-way valve in the chamber of a conventional spark discharge plasma jet (PSJ) generator to improve the air supply and the continuity of the jet during the suction and recovery stage of the generator. To obtain a higher energy synthetic jet. The optimization of the maximum jet velocity of the generator by different type of one-way valve under different loading parameters is studied, and the optimum working parameters of the air-supply plasma jet generator are determined by orthogonal experiment. To obtain the highest synthetic jet velocity. In this paper, the plasma jet generator is equipped with the selected air supply one-way valve, the optimal loading voltage frequency is 150 Hz, the amplitude is 50 kV, and the duty cycle is 15. The experimental results show that the maximum jet velocity is increased by more than 20% and the working frequency band of high jet velocity is extended from one point to 100 Hz in order to obtain better results when applied to flow control. The research results provide guidance for the subsequent application research of active flow control.
