中文摘要：
通过对连续相湍流导致的油滴聚合和破裂现象的合理模化，本文建立了适用于垂直上升管油水两相分散流的相界面浓度输运方程。其中对连续相湍流驱动油滴随机碰撞引起的聚合现象模化时，考虑了两油滴间连续相液膜排出过程中的凹面膜效应。而在描述油滴与湍流涡随机碰撞导致的破裂现象时，考虑了破裂过程所产生油滴的大小不等的因素。利用所建立的相界面浓度输运方程对沿实验段轴向的相界面浓度变化进行了预测，结果与实验数据比较表明吻合很好。
英文摘要：
With reasonable modeling of the mechanism of oil drop coalescence and breakup induced by turbulence, a new interracial area transport equation was established, which can dynamically describe the axial development of interracial area concentration of an oil-water two-phase dispersed flow in vertical upward pipe. When modeling oil drop coalescence mechanism induced by the random collisions between oil drops due to turbulence, a dimple phenomenon was considered to describe the drainage of continuous phase between two oil drops. And when modeling the mechanism of oil drop breakup induced by the random collision between oil drop and turbulent eddy, the two daughter oil drops may have a variety of size. The prediction made by the interracial area transport equation agrees well with experimental data of the axial development of interracial area concentration obtained in vertical upward oil-water two-phase dispersed flow.
