摘要
要使自激脉冲喷嘴产生良好的激振,影响自激腔内涡环结构的喷嘴腔体直径、腔体长度、上喷嘴直径、下喷嘴直径、碰撞壁中心角等参数必须相互配合.采用无量纲量,针对3种腔径、5种腔长、4种下喷嘴直径和1种上喷嘴直径配合而成的多种工况进行交叉数值分析.通过对数值模拟结果的分析,给出自激喷嘴结构参数的最优数值配比.
The parameters, which includes the diameter of the jet chamber, chamber length, the diameter of upper and lower jet, the center angle of the collapse wall, must match excellently to produce fine excited vibration. Dimensional analyses are employed to complete numerical simulation with a variety of states combining three chamber diameters, five chamber lengthes, four upper and one lower jet diameters. The numerical foundation of the optimization on the self-excited pulse jet is investigated through the analysis of the simulation results.
