| 摘 要： | 基于运动波理论本文建立了垂直上升管中油水两相流运动波传播方程,计算得到了管内无仪器插入体情况下油水两相流运动波传播速度特性曲线,根据曲线特征确定了油水两相流过渡流型存在于持水率大于0.25并小于0.5区间,应用该流型辨识准则对Govier等实验观察到的油水两相流流型试验点进行了辨识,取得了较好对比效果。此外还使用Flores等击碎聚合机理性模型验证了本文的辨识流型图,并与之结合产生了更加细化的合成流型图。

| Abstract: | Based on kinematic wave theory, the propagation equation of kinematic wave concerned about oil/water two phase flow in vertical upward pipes has been established and the characteristic curves of the kinematic wave propagation velocity for oil/water two phase flow without centre body have been achieved. According to the characteristics of the curves, it is determined that the transition flow pattern of oil/water two phase flow falls into the water hold-up range of 0.25
