摘要
通过对上喷嘴直径分别为 8mm和 10mm的低压大流量自激振荡脉冲射流喷嘴系统的试验研究得到了其结构参数的最佳配比关系 ,并与以往高压小流量自激振荡脉冲喷嘴优化的结构参数配比相比较 ,阐明了引发差异的原因。
Two low-press and amount-flux pulsation-jet nozzles of self-exicited oscillation 8mm and 10mm in diameter are studied in experiments, the optimized ratio of structure parameters are obtained, and the ratio differences between low-press amount-flux and high-press fewness-flux pulsation-jet nozzle are comepared and the causations are expatiated The results are important to the design of pulsation-jet nozzle.
