【摘要】 在石油行业真实管路流动中,几乎都伴有乳化剂的添加。然而由于气液两相流动的复杂特性,考虑乳化剂对气液两相垂直管流压降影响规律的研究工作,仍十分有限。本研究通过理论分析与实验研究相结合的手段,对伴有乳化剂添加的气液垂直管流流动特性和压降特征进行探讨。研究发现,乳化剂的添加可以促进流动更加趋于稳定。其结果有助于为今后研究工作提供参考。更多还原

【Abstract】 Almost every real flow case in the oil industry is with the addition of emulsifier.However,the research on the influence of emulsifier on pressure drops of vertical flow is limited,since the gas-liquid flow processing is very complex.In this paper,flow characteristics and pressure drops of gas-liquid vertical flows with emulsifier additive have all been discussed in the view of theoretical analysis and experimental measurement.It can be seen from the result,the flow tends to be more uniform with emulsifier additive,which must be as a reference for the future work.更多还原
