摘要
以输送稠油的90°弯管为研究对象,对稠油流经弯管进行流场和应力的分析。利用Anton Paar MCR302可视化流变仪测得了稠油的粘温曲线,并借助Fluent与Ansys软件对弯管进行热流固耦合模拟计算。对稠油样品在不同温度及流速下流经管道弯头进行了流场和应力的研究和分析。研究结论可为进一步研究稠油流经弯管的冲蚀机理提供理论依据。
The flow field and stress of heavy oil flowing throughout the 90-degree bend were analyzed. The viscosity of heavy oil at different temperature was measured by using Anton Paar MCR 302 rotary viscometer, and the viscosity-temperature curve was also analyzed with the regression analysis method. In addition, the fluid-solid-heat coupling of the bend was simulated by using Fluent software and Ansys software. The flow field and stress of heavy oil flowing throughout the bend at different temperature and velocity were analyzed. The research result can provide a theoretical foundation for further study on erosion mechanisms of heavy oil flowing throughout the bend.
