Abstract: Uneven distribution of gas-liquid two-phase flow in T-tube was easy to cause bias flow and uneven heating in heat exchangers. To optimize the gas-liquid two-phase flow in T-tube, the simulation about influences of flow parameters and tubes geometric structure on distribution of two-phase flow characteristics in T-tube was carried out by FLUENT. It was found that higher volume fraction of liquid phase and slower inlet velocity, and a smaller diameter of liquid drops facilitate even distribution of fluid. Meanwhile, the elbow structure was better than a straight tube at joints of branch tubes, the inlet velocity had most obvious influence on flow distribution, the difference of three units in speed could result in around 10% variation in volume fraction ration between two outlets. The results showed that change the flow parameters and tubes geometric structure correspond could optimize fluid flow in T-tube effectively.

Key words: uniform fluid distribution, flow parameters, geometric structure, numerical simulation, gas-liquid two-phase flow
