摘　　要：针对离心泵内流PIV测量仅能得到绝对速度的问题,根据速度三角形,采用Visual C++2010开发了能够处理2DPIV和3DPIV的离心泵PIV测量速度处理软件。采用该软件对双叶片离心泵叶轮内的绝对速度分布进行了处理,得到了叶轮流道内的相对速度、无量纲相对速度、相对液流角、动压、角动量等分布,并得到了不同半径上平均无量纲相对速度、平均相对液流角、平均动压以及平均角动量的变化趋势。结果表明,该软件能够处理不同比转数的离心泵PIV测量速度。Targeted at the problem which absolute velocity can be just obtained for PIV measurement ot centrilugal pumps, on the ba-sis of the velocity triangle, PIV velocity process software of centrifugal pumps is developed with Visual C＋＋ 2010. This software is able to process 2-D PIV measurement result as well as 3-D PIV. By using this software, absolute velocity distribution in a double-blade centrifugal pump impeller is processed. The relative velocity, dimensionless relative velocity, relative fluid flow angle, dynamic pressure and angular momentum in the impeller are obtained. Variation tendency of average dimensionless relative velocity, average relative fluid flow angle, average dynamic pressure and average angular momentum in different radius are gotten. The results show that the software is able to process PIV measurement velocity of centrifugal pumps with different specific speeds.
