摘　　要：对水平管内油 -气 -水三相间歇流向环状流转换特性进行了理论和实验研究 ,建立了间歇流向环状流转变的界限方程。结果表明 :间歇流向环状流转变的主要因素是气相折算速度和液相折算速度 ,含油率与管径的影响不大。计算结果与实验结果基本吻合。An experimental and theoretical study was conducted of the intermittent-to-annular flow transition of oil-gas-water three-phase flow in a horizontal tube. Proposed was a boundary equation featuring the transition of the intermittent-to-annular flow. The experimental study results show that the major factor governing the transition of the intermittent-to-annular flow is the gas-phase reduced speed and the liquid-phase reduced one with the effect of oil fraction and tube diameter playing an insignificant role. The results of calculation have been found to be basically in agreement with those of experiment.
