摘要
Generally, crude oil has been transported via pipelines. But sand particles normally will be deposited on the bottom of pipeline due to the unsteady flow which it can lead to flow concern and erosion deformation of the pipe wall if not well treated. As well, this issue can cause the pipe destruction and burden the maintenance cost if not prevented in the early stage. Thus, this study was simulated to observe and predict the erosion rate at various parameter conditions with presence of solid particles in pipeline surface via COMSOL© Multiphysics 5.4 software. The model of k-ω turbulent and particle tracing were applied where several different potential impacting factors on the formation of erosion were investigated including fluids flow velocity, sand particle size, sand flow rates, pipe orientation and pipe diameter. The result simulation showed the area around the bend pipe had high predictions of erosion deformation where the maximum erosion rate of 732 mg/m2s was observed for 2-inch pipe diameter and 100mm particle size. Besides, it shows the erosion rate increased as the higher mass flow rate and fluid velocity. By applying these erosion models, it could be possible to foresee the maximum point of erosion deformation along the pipelines which can reduce maintenance cost and prevent flow assurance issues.
