摘要
基于计算流体动力学方法,运用雷诺应力模型(Reynold Stress Model,RSM)对一种新型脱油除砂三相一体化分离器内部流场特性和分离性能进行数值模拟分析,得出了介质粘度对三相分离器脱油除砂性能的影响规律。结果表明:介质粘度在1.6~2.8mPa·s范围内变化时,随着粘度的增大,分离效率呈逐渐降低趋势,最佳工况下三相分离器的除砂效率达到93%,除油效率可达95%,呈现出了较好的脱油除砂效果。
Based on the computational fluid dynamics(CFD), the flow field and separation performance of a new three-phase separator for the de-oiling and sand removal was analyzed by using Reynolds stress model(RSM). Systematically analyzing the influence of viscosity condition of the same medium on the de-oiling and sand-removing performance of the three phase separator shows that, the separation efficiency decreases with the increase of viscosity at the range between 1.6 mPa·s and 2.8 mPa·s. The highest sand removal efficiency is 93% and the oil removal efficiency is more than 95%, which shows a good application prospect.
