摘要
应用标准к-ε模型和多相混合模型,对重力式油气分离器内聚结元件分离流场进行了数值模拟,通过比较含有竖向平行板、蛇形相向、相背平行板和田字板4种不同聚结元件的分离器内部流场中速度矢量和各相体积分数分布,得到了不同构件的聚结特性.结果表明,聚结元件具有稳定流场,抑制涡流,对液滴进行有效聚结的优点,其中田字型板聚结元件效果最优,蛇形相向平行聚结板次之,而竖向平行板聚结元件的聚结效果最差.为分离器的设计提供了参考依据.
The numerical simulation of oil/gas separation flow field in a gravitational separator with different coalescing components,including parallel plates,opponent snake-shaped curve plates,antitropic snake-shaped curve plates and grid-shaped plates,is carried out by using standard κ-ε model and multiphase mixture model.The coalescing performance of different components is obtained by comparing the velocity vector and every phase volume fraction distribution in the separation flow field inside the separator with four different coalescing components.The simulation results show that,the coalescing component composed of grid-shaped plates has the best coalescing liquid effect,the coalescing component composed of antitropic snake-shaped curve plates is secondary,and the coalescing component composed of parallel plates has the worst coalescing liquid effect.The simulation results can provide help for the design of oil/gas separators.
