摘　　要：详细介绍了PIV的工作原理、数据处理流程和使用要点。针对涡轮内部复杂的流动特性,应用具有较高空间分辨率的非接触式瞬态速度的PIV测量技术,获得了较清晰完整的沿叶高平面和叶栅出口速度场的瞬时速度场信息,并据此分析了涡轮静叶出口二次流的流动特性,为叶栅流场优化提供了有益的参考。PIV is a new measure instrument, which has better merit than others especially for complex flow field. The working rule, disposal flow chart and operation outline of PIV are introduced in detail. Finally,an example is used to measure the instantaneous entire velocity field along blade height and outlet plane with PIV. As a result,it is satisfied and beneficial to optimize the blade flow field.
