The flow field around a hydrophone generates self-noise which may contaminate the sound-field detection by a hydrophone. Hence, four hydrophone dome models are designed, and the flow field and sound field around them are compared. The RNG k–ε turbulence model is used for steady calculation. The results show that the four models have a fine diversion effect, and there is no obvious vortex and circumfluence because of them. The Curle model is used to simulate the sound source calculation of the hydrophone dome. The leading edge area of each model is found as the main noise source. The large eddy simulation/FW-H hybrid method is applied for the acoustic field calculation. The flow noise around the four models is studied. By summarizing the results of different models, the rules of flow noise around the hydrophone domes are analyzed. The suggestions for the hydrophone dome design are given based on the comprehensive evaluation of the noise generated by each hydrophone dome.

水听器周围的流场会产生自噪声，这可能会污染水听器的声场检测。因此，设计了四个水听器圆顶模型，并比较了它们周围的流场和声场。RNG k – ε湍流模型用于稳态计算。结果表明，4个模型均具有良好的导流效果，未出现明显的涡流和回流。Curle模型用于模拟水听器球罩的声源计算。每个模型的前沿区域被认为是主要的噪声源。声场计算采用大涡模拟/FW-H混合法。研究了四个模型周围的流动噪声。通过总结不同模型的结果，分析了水听器穹顶周围流动噪声的规律。在对每个水听器球罩产生的噪声进行综合评估的基础上，给出了水听器球罩设计的建议。
