Cavitation Erosion Behavior in Different Throttling Pipelines

摘要：

　　Throttling pipelines arc adopted to improve their cavitation erosion resistance,while there often exists cavitation erosion,large energy loss and big noise in throttling pipelines.In this study,the three-dimensional (3D) model of the secondary throttling pipeline was constructed according to the actual structure and parameters.It has been calculated that compared to the ordinary throttling pipeline,the secondary throttling pipeline makes the maximum velocitydecreased from 19.827 to 19.168 m/s,and the minimum negative pressure increased from-2.02 to-1.77 MPa.The results is significant for choosing and designing the throttling pipelines.
