Improvements on Throttling Pipelines Basing on Numerical Simulation

Abstract:

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.
