Effect of choke pipe diameter on the chocking-cavitation characteristics

Under the condition of different choke pipe diameters, the choking-cavitator was made numerical analysis by Fluent software and the cavitation noise signals were tested. The effect of the diameters on the cavitation characteristics of chocking-cavitator was investigated. It is shown that as the choke pipe diameters increases, the maximum pressure gradient increases and the choking section moves to the choke pipe upstream. The numerical analysis on the choking-cavitator is consistent with the cavitation noise signals test results, and the best diameter is 10 mm.
