Numerical Study of the Erosion Distribution of Sulfur-Containing Particulate Gas in 90-Degree Gathering Elbow

The phenomenon of pipeline erosion dominated by sulfur particles has become a key research target for sulfur-containing gas-gathering pipelines. Gas-solid two-phase flow gases is simulated with coupled CFD-DPM model in this paper. Realizable k-ε turbulence was used to determine the changes complex field and Euler-Lagrange method describe specific trajectory field. main trace distribution effect secondary effects at elbow were analyzed pattern investigated different curvature ratios, particle sizes, pipe diameters. results show that formation along tip V-shaped on outlet sidewall may be related effects. increase ratio RD reduces intensity maximum area, but subsequent will result new near reach when = 8. Variations size have significant extent distribution, causing vary between 48.2° 84.2°, while variations diameter lesser effect. Stokes number can also reduced controlling variation alter force profile reduce
