摘要
基于Fluent对全尺寸自激振脉冲射流喷嘴进行仿真研究,要使自激振脉冲喷嘴产生良好的自激振效果,喷嘴腔体直径、腔体长度、上喷嘴直径、下喷嘴直径、碰撞中心角等参数必须相互配合。采用无量纲量,针对不同腔径、腔长、下喷嘴直径配合而成的多种工况进行仿真分析,得到自激振喷嘴最优的结构参数。
Studying on the full-size structural optimization of pulsed jet nozzles by Fluent is to produce a fine selfexcited vibration.If pulsed jet nozzles work well,the parameters,which include the diameter of the jet chamber,chamber length,the diameter of upper and lower jet,the center angle of the collapse wall,have to match excellently.Dimensional analyses are employed to complete the simulation analysis with different chamber diameters,chamber length,upper and lower jet diameters.So,we can obtain optimal structural parameters.
