摘要
为降低通海管路出水管末端管径对水动力噪声的影响,对出水管末端管径提出多种扩大方案,并采用数值仿真方法计算了多种管径尺寸下的噪声和流速分布情况。研究结果表明,通海管路出水管末端管径扩大1.1倍时,总声压级达到最小值,减振降噪效果最佳。
In order to reduce the influence of terminal diameter for outlet-water in seawater pipeline on hydrodynamic noise,a variety of amplification schemes were put forward for terminal diameter of outlet-water,the noise and flow velocity were simulated in a variety of diameter dimensions.The results showed that when the terminal diameter for outlet-water in seawater pipeline expands 1.1 times,the OSPLs reach the minimum;it has the best effect of damping vibration and noise.
