油气分离器内整流元件分离流场的数值模拟

为探讨分离器内整流元件的性能优劣,应用标准к-ε模型和多相混合模型,对油气分离器内整流元件分离流场进行了三维数值模拟.通过比较含有4种不同整流元件的分离器内部流场中速度矢量和各相体积分数分布,并与没有整流元件的分离流场进行对比,得到了不同构件的整流特性.研究结果表明,整流元件具有稳定流场、降低流速、抑制涡流的优点,其中田字型板整流元件效果最优,横向平行板次之,而同心圆筒板整流元件的整流效果较差.

Numerical simulation of the flow field inside the oil-gas separators with different regulating components

In order to research the performance of the different regulating components inside the oil-gas separators,the 3D numerical simulation of the oil-gas separation flow field in a separator with different regulating components is carried out by using a standard κ-ε model and a multiphase mixing model.The velocity vector and the phase volume fraction distribution inside the separators with four different regulating components are gained,and the flow field-regulating performance of the four components is obtained by comparing the velocity vector and the phase volume fraction distributions with the flow field inside the separator without any regulating component.The simulation results show that the regulating components have the advantages of stabilizing the flow field,reducing the flow velocity and inhibiting vortex.Among the four components,the performance of the grate plates-type flow-regulating component is the best,the horizontal parallel plates-type flow-regulating component is secondary,the vertical parallel plates-type flow-regulating component is the third,and the columnar concentric plates-type flow-regulating component is the worst.
