摘要:
随着江苏境内泵站改造工作的开展，泵内部流体非定常流动引起的流致噪声越来越成为影响环境的突出问题。针对在实际运行中噪声问题较为严重的沙集泵站，采用CFD/CA相结合的数值模拟方法，对比分析不同流量工况下叶片偶极子声源诱导的泵内流致噪声特性。计算结果表明，叶片偶极子声源诱导的流致噪声主要包括宽频噪声和离散噪声，声压级主频为叶频（20 Hz）；在叶片偶极子声源的影响下，声压级较大值主要出现在叶轮进口附近，小流量工况下诱发的流致噪声最为强烈。
Abstract:
With the development of pumping station reconstruction in Jiangsu, the flow-induced noise caused by the unsteady flow of fluid inside the pump has increasingly become a prominent problem affecting the environment. Aiming at the Shaji pumping station with serious noise problems in actual operation, the numerical simulation method combining CFD/CA was used to compare and analyze the flow-induced noise characteristics in the pump induced by the vane dipole sound source under different flow conditions. The calculation results show that the flow-induced noise induced by the vane dipole sound source mainly includes broadband noise and discrete noise, and the main frequency of the sound pressure level is the vane frequency（20 Hz）. The large value mainly occurs near the inlet of the impeller, and the flow-induced noise is the most intense under the condition of small flow.
