中文摘要:
      目的 研究海水管道在振动工况下受冰晶颗粒的冲蚀磨损规律,提出极地船海水管道系统优化措施,保障船舶在极地区域安全航行。方法 通过CFD(计算流体动力学)中的离散相模型、冲蚀磨损模型和动网格技术,研究不同振动工况下冰晶两相流对水平和竖直方向布置的90°弯管冲蚀磨损特性,预测管道使用寿命变化情况。结果 弯管磨损严重区域随振动工况发生改变,振动对水平弯管的磨损比对竖直弯管的大;振幅一定时,竖直弯管使用寿命均高于水平弯管,水平弯管从218.64 d降低到最小的12.75 d,竖直弯管从332.40 d降到43.12 d。振幅为1 mm时,水平弯管在频率为10~20 Hz之间出现使用时间转折突变的现象,从112.01 d增大到173.24 d,然后又大幅减小。结论 振动对90°海水管道的使用寿命产生显著影响,80 Hz、2 mm振动工况的管道使用寿命比无振动时减少了205.89天。
英文摘要:
      The work aims to study erosion law of seawater pipelines by ice particles under vibration condition, and put forward optimization measures for seawater pipeline system to ensure safe sail in polar region. Discrete phase model, erosion wear model and dynamic grid technology in CFD (computational fluid dynamics) were employed to study erosive wear characteristics of horizontally and vertically arranged 90° elbows by ice crystals under different vibration conditions. Service life variation of the pipelines was predicted. Vibration would change the seriously worn position of the elbows. The effect of vibration on horizontal elbows was greater than that on the vertical elbows. When the amplitude was constant, service life of the vertical elbows was longer than that of the horizontal elbows. Service life of the horizontal elbows decreased from 218.64 days to the minimum, 12.75 days while that of vertical elbows decreased from 332.40 days to 43.12 days. At the amplitude of 1mm and frequency of 10~20 Hz, service time of the horizontal elbows changed abruptly from 112.01 days to 173.24 days, and then reduced significantly. Vibration has significant effects on service life of 90° seawater pipelines. Service life of pipelines subject to 80 Hz, 2 mm vibration is 205.89 days shorter than that of original ones.
