摘要
采用可以获得瞬时速度场的PIV技术,对有叶扩压器入口区域的非流动进行了实验研究,对实验数据采用锁相平均法进行了处理,得到了显示一个周期内不同时刻有叶扩压器入口区域的速度场分布图并对其进行了分析和讨论。
The PIV system wbich that can record the instantaneous flow field was used to research the flow within the inlet region of vaned diffuser. The experimental data were averaged by Phase-locked averaged Method. The velocity vector distributions when impeller was located in different relative position were got out and analyzed.
