有叶扩压器内部流场的PIV实验测量

PIV (Particle Image Velocimetry) Experimental Measurements of the Flow Field in a Bladed Diffuser

采用可以获得瞬时速度场的PIV技术对有叶扩压器内的流动进行了实验研究 ,测量了不同流量工况下的有叶扩压器内部流场 ,对实验数据采用整体平均法进行了处理 ,得到了显示各流量工况下的速度场分布图 ,并对其进行了分析和讨论。

By making use of PIV (particle image velocimetry) techniques capable of acquiring an instantaneous velocity field an experimental investigation is conducted of the flow in a bladed diffuser. The flow field in the diffuser at different flow conditions was measured. The test data were processed by the use of an integral averaged method and diagrams showing velocity field distribution at various flow conditions were obtained. An analysis and discussion of the above was also conducted.
