Multiphase phenomena are observed in our everyday life in nature and many industrial applications, ranging from dew condensation on insects, water harvesting, electronics cooling, climatology prediction, hydrogen generations, and manufacturing. While the fundamentals of multiphase processes have been studied for over a century, key scientific questions remain regarding the fundamental mechanisms governing complex phenomena. The intricate interplay between the evolution of phase boundaries and mass transport results in nonlinear behavior, where subtle changes in one parameter can have profound and unexpected effects on others. The multimodal, multidimensional, and transient nature of these processes presents challenges for investigation and comprehension. Additionally, interpreting experimental data and predicting multiphase phenomena remain significant challenges. Central to unraveling these complexities is the extraction of interpretable and rich datasets from dynamic visual information around phase boundaries, such as bubbles, droplets, or interfaces. To address these challenges, our research group seeks to integrate cutting-edge computer vision and machine learning strategies. In this talk, I will showcase key approaches developed by my group that reveal previously undefined features and hidden mechanisms. Furthermore, I will introduce examples illustrating how AI technologies enable learning, understanding, and prediction of the dynamic nature of multiphase phenomena. In conclusion, this talk will briefly discuss potential game-changing innovations for energy and water applications, exploring the exciting opportunities that arise from the intersection of multiphase physics and advanced technologies.
