Abstract

Abstract: In order to study the erosion and wear of elbows caused by solid-liquid two-phase flow, CFD numerical simulation of elbows with different geometric parameters was carried out based on hydrodynamics and tribology theory. The rules of geometric parameters and wear rate of elbows were summarized, and the wear mechanism of pipelines was analysed with related theories. The main conclusions are as follows: the maximum erosion rate decreases with the increase of the pipe diameter and bending angle and increases with the increase of the pipe length and bending radius. Among the above factors, the bending angle has the greatest impact on the maximum erosion rate of the pipeline.
