摘　　要：对三维粒子动态分析仪(3D PDA)和测量原理进行了介绍,同时利用该设备对撞击流混合器流场进行了湍流测量和流场分析,给出了混合器内时均速度场分布、脉动速度等的实验结果,为撞击流混合器的设计和放大提供有价值的实验数据。The measuring instrument and primary methods of a three-component Particle Dynamics Analyzer were introduced. An experimental investigation of the flow field in the impinging stream mixer was presented. The experimental results provided the mean velocity, fluctuation velocity in the mixer. This study provided the valuable references for the further optimization and enlargement of the impinging stream mixer.
