要約

Wear due to particles is often the key factor for pipeline failure. In this work, the effects of different sand particle concentration on the erosion of a vortex-chamber elbow are investigated numerically. Based on four-way-coupled simulations of the gas-solid flow, the comparison between the standard and vortex-chamber elbow results was performed and a detailed analysis of the mass loading influence on the penetration ratio was carried out. An important finding is that the addition of the vortex chamber significantly shows the efficiency of the cushioning effect. A comparison of the peak of penetration ratio in both elbow designs, for a mass loading of 1.0, indicates that the reduction was around 93% when the vortex chamber is present.
