摘　　要：试制一种特殊的T型三通管结构取样器,8个取样孔均匀布置在管壁周围,取样孔上游布置有旋流叶片用于流型调整。研究气液两相流通过该分配器的流动特性。采用Euler气液两相流模型和雷诺应力模型,通过数值模拟方法分析节流元件尺寸对分配器分流特性的影响,并在多相流试验环道上开展试验研究。结果表明:旋流取样分配器特性受节流元件尺寸影响显著,前后压力场的变化是分流系数发生变化的根本原因。A specially designed T-junction type distributor was proposed. The swirled sampling distributor has 8 sampling holes along the circumference of the pipe wall and a swirl element was mounted upstream for flow pattern adjustment. Euler muhiphase flow model and Reynolds stress model were constructed to simulate the flow characteristics when gas-liquid two- phase flow passing the distributor. The effects of throttle sizes of the swirled sampling distributer on the extracting characteris- tics were numerically simulated. The experimental tests were carried out at air-water two phase flow loop to study splitting characteristics of the distributor. The results show that the effects of throttling element on the characteristics of cyclone sam- plers are significant. The change of pressure field is the most fundamental reason of the change of split coefficient.
