摘　　要：本文针对R410A喷射式系统气液分离器入口干度低的特点,开发了新型旋流式气液分离器。通过研究高度、直径和气相管插入深度等关键结构参数对气液分离器分离效率以及压降的影响,将这些结构参数进行仿真优化,得到最优气液分离器模型,然后进行实验,对比仿真数据与实验数据。不同工况下,新型气液分离器压降与气相出口干度的仿真结果与实验结果误差在10%以内,计算流体力学(Computational Fluid Dynamics,CFD)的仿真模型具有较高精度。In the present study,a new cyclone type gas-liquid separator was developed aming at the characteristic of low inlet vapor quality for gas-liquid separator of R410 A ejector system.By studying the effects of key structural parameters such as the height,diameter and gas pipe insertion depth on the separation efficiency and pressure drop of gas-liquid separator,the structure parameters were optimized by simulation and the optimal gas-liquid separator model was obtained.The experiments were carried out by using the optimal model,and the simulation results were compared with the experimental data.Under different working conditions,the errors between simulated and experimental results of the new gas-liquid separator pressure drop and gas outlet dry degree were less than 10%,thus the Computational Fluid Dynamics（CFD） simulation model has a high accuracy.
