中文摘要:
      在管道输送过程中,油品中夹带的微小固体颗粒会对管道壁面产生冲蚀磨损。采用DPM冲蚀预测模型,模拟在不同流速、不同颗粒直径、不同质量流量下管道的冲蚀分布规律,预测异面三通管中受冲蚀磨损比较严重的区域。结果表明:固体颗粒对异面三通管的冲蚀主要集中在三管交汇处的弯面、水平管段的上侧管壁以及两水平管的交汇处,对管道弯头底部的冲蚀较小;管道的最大冲蚀率随流体入口速度的增大呈指数增长;管道的最大冲蚀率随颗粒直径的增大开始时缓慢增大,当颗粒直径增大到一定值时管道的最大冲蚀率随之呈线性增长趋势;管道的最大冲蚀率随着颗粒的质量流量的增大且呈线性增长。
英文摘要:
      The solid particles in the oil may cause erosion wear on the wall of pipeline in the process of oil transportation.DPM erosion model was used to predict the erosion area on the tee in different planes by changing the inlet velocity,particle diameter and particle mass flow rate.The results show that the erosion wear of tee in different planes is mainly concentrated on the curved surface in the junction of three pipes,the upper wall of the horizontal pipes and the junction of two horizontal pipes,while the erosion wear on the bottom of pipe bend is smaller.As the inlet velocity increasing,the maximum erosion rate of pipe is increased exponentially.The maximum erosion rate of pipe is firstly increased slowly with the increasing of particle diameter,then increased linearly when the particle diameter is increased to a certain value.With the increase of particle mass flow rate,the maximum erosion rate of pipe is increased linearly.
