摘　　要：在不同壅塞管直径下,利用Fluent软件对壅塞空化器进行数值分析并采用水听器对其空化噪声信号测试,探索壅塞管直径对壅塞空化器空化特性的影响。测试结果表明:增大壅塞管直径,最大压力上升梯度值会增大,壅塞截面会向上游移动;壅塞空化器的数值分析和空化噪声信号测试结果基本吻合,壅塞管的最佳直径为10 mm。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 will increase and the choked section will move 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.
