Uncovering dynamic behaviors underlying experimental oil-water two-phase flow based on dynamic segmentation algorithm

► We use dynamic segmentation algorithm to uncover the dynamic flow behavior. ► We extract statistic associated with chaotic dynamics from experimental signals. ► The statistic is sensitive to the transition among different oil-water flow patterns. ► Our method can yield quantitative insights into the dynamic behavior of flow patterns. ► Broader applicability of our method is demonstrated and articulated.
