Matter exists in different phases—solid, liquid, and gas—depending on temperature and pressure. Flows in which these phases coexist are known as multiphase flows. My research focuses on dispersed multiphase flows, particularly those containing bubbles and droplets, with the goal of understanding their microstructure and hydrodynamic interactions. For example, bubbles rising in liquids play key roles in many industrial systems, including chemical reactors and environmental processes. However, their collective behavior—arising from bubble–bubble interactions and wake dynamics—remains only partially understood. Clarifying these fundamental mechanisms can contribute to the development of more efficient multiphase reactors and transport processes. My research also explores engineering applications of dispersed flows. When droplets suspended in a gas impact a solid surface, they generate mechanical actions such as impact forces and shear stresses. By utilizing these effects, it is possible to develop novel chemical-free cleaning technologies for advanced manufacturing processes. Through these studies, I aim to bridge fundamental fluid mechanics of dispersed multiphase flows with practical applications, including cleaning technologies for manufacturing and measurement techniques for capturing these complex phenomena.
