【摘要】：T形多分支管作为新型气液分离构件,具有紧凑、稳定、经济等优点。采用混合k-ε湍流模型与欧拉多相流模型对T形多分支管中的气液两相流动进行了模拟分析,考察了其结构参数的变化对分离性能的影响。结果表明,结构一定的T形多分支管,确定的进出口边界条件决定了唯一的水力平衡系统,流体所具有的能量在管路中自由分配直至达到平衡,分流促进了气液两相的分离。分支管间距增大,能使气液两相分离效率得到显著提高,但增幅逐渐降低;分支管高度、管径增大时,分离效率均呈现先增大后减小的趋势;分支管结构参数的变化促使流体流动方向发生改变,进而影响分离效率。
[Abstract]:As a new gas-liquid separation component, T-shaped multi-branch tube has the advantages of compact, stable and economical. The mixed k- 蔚 turbulence model and Eulerian multiphase flow model were used to simulate the gas-liquid two-phase flow in a T-shaped multi-branch tube. The influence of the structural parameters on the separation performance was investigated. The results show that the inlet and outlet boundary conditions of a certain T-shaped multi-branch pipe determine the unique hydraulic equilibrium system, the energy of the fluid is freely distributed in the pipeline until the equilibrium is reached, and the separation of gas-liquid two phases is promoted by the separation of the gas and liquid phases. The separation efficiency of gas-liquid two-phase separation increases significantly with the increase of branch tube spacing, but the increase decreases gradually, and the separation efficiency increases first and then decreases with the increase of branch tube height and pipe diameter. The change of the structural parameters of the branched tube leads to the change of the flow direction of the fluid, thus affecting the separation efficiency.
