针对船舶通海管路系统，对低航速下管路的流场与噪声情况进行研究。通过引入体积力技术，模拟在低航速时由于水下航行体冷却系统的作用，冷却水流需要不断与外界交换的情况下，对管路排水引起的噪声情况进行分析，通过仿真计算得到低航速管路系统的流场情况与声压频谱情况，可知，体积力的作用可很好地推动水流流入管道，为低航速下管路系统的噪声计算提供参考。
A study was conducted on the flow field and noise situation of the ship’s sea pipeline system at low speeds. By introducing volumetric force technology, the noise caused by pipeline drainage was analyzed under the continuous exchange of cooling water flow with the outside world due to the cooling system of underwater vehicles at low speeds. The flow field and sound pressure spectrum of the low-speed pipeline system were obtained through simulation calculations. It can be concluded that the effect of volumetric force can effectively promote water flow into the pipeline, providing a reference for noise calculation of pipeline systems at low speeds.
