摘要
旋流分离器具有结构紧凑、价格低廉及应用广泛的特点,在近二十年里已经被广泛应用于油田的分离工艺之中。采用计算流体力学软件FLUENT对旋流分离器内部流场特征进行数值模拟,选取湍流模型为RNGk-ε模型,多相流采用欧拉模型,模拟考察了在不同进气口流速和不同底部锥角的情况下,旋流分离器溢流口处气液浓度的变化规律。计算结果表明,增加进口气-液介质的流速,分离器效率提高不明显;增大旋流分离器底部锥角,有利于气-液分离。
Cyclone separator has been widely used in oilfield separation process because of its compact structure,inexpensive and convenient application in recent twenty years.The numerical simulation for the cyclone separator inner flow field characteristics was performed by using computational fluid dynamics software FLUENT with the RNGk-εturbulence model and Euler multiphase flow model.In different intake port flow rates and different bottom of the cone angle case,the law of gas-liquid concentration variation of the cyclone separator overflow mouth was gained.According to the simulation,the separating efficiency increase is not obvious to the increase of imported medium（gas-liquid）flow rates;increasing the bottom of the cone angle is beneficial to the vapor-liquid separation.The simulation results provide a reference basis to the optimized design of the cyclone separator and enhance the separated efficiency.
