摘　　要：针对商用水冷螺杆机组的内置油分离器,采用Fluent软件对冷媒两相流场进行了数值模拟。先用RNG k-!模型计算连续相的气态冷媒,得到油分离器内流场参数分布特征,再加入离散相的液态油滴进行计算。最终依据仿真数据,计算获得油分离器的分离效率,并分析影响油分离器分离效率的因素,为油分离器的优化设计提供理论依据。For the internal oil separator of a screw type unit,Fluent was used to simulate the two-phase flow field.The RNG k-ε model is used to calculate the continuous phase to obtain the distribution characteristics of the flow field in the oil separator. Then add the discrete liquid oil droplets to calculation. Finally,based on the simulation data,the separation efficiency of the oil separator was calculated,and the factors influencing the separation efficiency of the oil separator were analyzed to provide a theoretical basis for the optimal design of the oil separator.
