摘要? 石油行業(yè)中的復雜管路通常由各種不同的管道和管件通過串聯(lián)或并聯(lián)組合而成,，油水兩相混合流動是其中最常見的流動形式。目前對復雜管路的研究主要局限于單一恒徑管道,。本文基于管路串并聯(lián)理論,、流型轉變準則、雙流體模型和均相流模型,，建立了復雜管路油水兩相流動的統(tǒng)一機理模型,，通過實例對該模型進行了驗證，并與數值模擬結果進行了比較,。研究結果表明,，該模型對油水兩相在復雜管路中的分流情況和壓降均表現(xiàn)出了良好的預測性，在體積含水率為 0%~100%條件下,，模型預測的絕對平均偏差最高為 14.4%,，總體平均偏差為 9.8%。

Abstract：

Oil-water two-phase flow in a complex pipeline, consisting of varying pipes and fittings in series/parallel, is commonly encountered in the petroleum industry. However, previous study has been mainly limited to a single constant-radius pipe. In this paper, a unified model of oil-water two-phase flow in a complex pipeline is developed based on the combination of pipe serial-parallel theory, flow pattern transformation criterion, two-fluid and homogenous models. A case is presented to verify the unified model and compare with CFD results. The results show that the unified model performs well in predicting both the flow distribution and pressure drops of oil-water two-phase flow in a complex pipeline. Compared with CFD results for water volumetric fractions ranging from 0% to 100%, the highest absolute percentage errors of the proposed model is 14.4% and the average is 9.8%.
