摘要
为了研究输油管道系统的冲蚀磨损问题,运用ANSYS FLUENT软件,通过改变管道进口流速、颗粒质量流量、颗粒直径,对90°弯管的流场分布及磨损情况进行了数值模拟。结果表明,随着进口流速的增加,弯管的冲蚀率逐渐上升;随着颗粒直径的增大,弯管的冲蚀率总体呈下降趋势;随着颗粒质量流量的增大,弯管的冲蚀率基本呈线性增长;进口流速、颗粒质量流量、颗粒直径等3个冲蚀影响因素之间存在交互作用。
For the problem of erosion-corrosion in oil pipeline system,used ANSYS FLUENT software,by changed the inlet velocity,the particle mass flow rate and the particle diameter,conducted numerical simulation for flow field distribution and severe erosion area of 90°elbow pipe.The results show that:with the increase of inlet velocity,the pipe erosion rate increases gradually;with the increase of particle diameter,the pipe erosion rate decreases;with the increase of particle mass flow rate,the pipe erosion rate increases linearly;and there have interaction between the three erosion factors of inlet velocity,particle mass flow rate and particle diameter.
