| 摘 要： | 采用ＤＡＮＴＥＣ公司的三维激光动态粒子分析仪（Ｄｕａｌ ＰＤＡ）测定了大喷嘴间距同轴对置两流肌及四流肌撞击后的径向速度分布。实验结果表明不同喷嘴直径及射流速度时大喷嘴间距两汉肌及四汉肌撞击后的最大径向速度与射流初速度、喷嘴直径和喷嘴间距有关，最大径向速度对应的径向距离与喷嘴直径无关，径向速度分布具有相似性。

| Abstract: | The radial velocities of wide spaced two jet and four jet impinging streams have been measured by Dual PDA with different nozzle diameters and primary velocities. Results show that the distribution of radial velocity of wide spaced two jet and four jet impinging streams has relation to d/L , the maximum radial velocity has relation to u 0 d/L , and the radial distance of the position of the maximum radial velocity is directly proportional to L . |
