Improvements on Throttling Pipelines Basing on Numerical Simulation

摘要：

　　The secondary throttling pipelines are adopted to improve their cavitation erosion resistance.With the aid of the finite element methods,under the conditions of the inlet velocity of 9 m/s and outlet pressure of zero,it has been calculated that compared to the ordinary throttling pipeline,the secondary throttling pipeline makes the maximum velocity decreased from 43.972 to 39.575 m/s,and the minimum negative pressure increased from-19.39 to-16.04 MPa.The secondary structure of the throttling pipeline has some good effect on the cavitation erosion resistance.
