【摘要】：T形多分支管作為新型氣液分離構(gòu)件,具有緊湊、穩(wěn)定、經(jīng)濟(jì)等優(yōu)點(diǎn)。采用混合k-ε湍流模型與歐拉多相流模型對(duì)T形多分支管中的氣液兩相流動(dòng)進(jìn)行了模擬分析,考察了其結(jié)構(gòu)參數(shù)的變化對(duì)分離性能的影響。結(jié)果表明,結(jié)構(gòu)一定的T形多分支管,確定的進(jìn)出口邊界條件決定了唯一的水力平衡系統(tǒng),流體所具有的能量在管路中自由分配直至達(dá)到平衡,分流促進(jìn)了氣液兩相的分離。分支管間距增大,能使氣液兩相分離效率得到顯著提高,但增幅逐漸降低;分支管高度、管徑增大時(shí),分離效率均呈現(xiàn)先增大后減小的趨勢(shì);分支管結(jié)構(gòu)參數(shù)的變化促使流體流動(dòng)方向發(fā)生改變,進(jìn)而影響分離效率。
[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.
