We are developing prediction and measurement methods for various fluid phenomena. From the perspectives of avoiding negative effects, and utilizing and controlling passive/positive functions, we are addressing issues aimed at applications of e.g. carbon neutrality and medical engineering. For example, we are tackling challenges through experiments, theory, and numerical simulation for research subjects such as elucidating and utilizing multiphase, reactive and liquid metal flows, developing large-scale/multi-scale and hybrid analysis methods, and analyzing various fluid-structure interaction problems.
