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.
