摘要：
According to the diversity of fluid composition and the complexity of flow pattern of rainwater ill the pipeline, a flow velocity measurement method based on cross-correlation analysis is proposed, reference flow filed measurement technique in Particle Image Velocimetry. The fast algorithm of cross-correlation analysis is studied. Established a pipeline rainwater calibration device using weir slot. The results show that extracting all average speed from the velocity field can smooth the flow variability and accurately measure the average velocity of rainwater.
