Abstract In the process of CO2 pipeline transportation, the frequent use of elbow is more likely to cause erosion damage to straight pipe. CO2 solid hydrate is an important factor causing the erosion damage of CO2 elbow, so it is very important for the study on erosion of elbow. The supercritical CO2 elbow model was established by FLUENT software, and the effects of CO2 solid hydrate on the erosion damage degree of elbow under different inlet velocity, different elbow curvature radius and different elbow bending angle were simulated and analyzed. The results show that when the inlet velocity is 2.5 ~ 3.0 m / s, the maximum erosion rate at the elbow is in a low range; when the curvature radius of the bend R≥2.0 DN, the maximum erosion rate at the elbow is at a low value; when the bending angle of the bend is ≥ 110 °, the maximum erosion rate of the bend is low. The research results can provide a theoretical basis for CO2 pipeline transportation and supercritical CO2 pipeline erosion research in China.

Key words： CO2 solid hydrate supercritical CO2 elbow； erosion numerical simulation pipeline transportation
