摘要
Abstract
The erosion characteristics of elbows are numerical simulated by computational fluid dynamics and discrete element coupling method(CFD-DEM).The aforementioned flow characteristics are important factors to ensure stable and reliable transportation of side injection for coal powder particles in nonferrous metal smelting.The ordinary elbows,the T-shaped elbows,the blind elbows,and spherical elbows are selected to discuss.The results show that the erosion area of T-shaped elbows is mainly concentrated on the below section near the outlet of the elbow,while that of the blind elbow is mainly concentrated at the convex edges.The erosion area of spherical elbow is mainly concentrated in the first impact area of particles.Meanwhile,the blind elbow has the highest uniform collision strength concentrated at the convex edges of the elbow.The maximum erosion rate of the blind elbow is the highest relative the smallest spherical elbow.关键词
