Outline Activities
I am interested in thermal fluid dynamics inside aircraft, rocket and satellite engines, and multiphase phenomena in energy, food and sparklers. By visualizing the phenomena beautifully and formulating them elegantly, we understand the essence of complex phenomena and obtain useful knowledge for actual design.
Lectures are given in Advanced Propulsion Engineering (graduate school) and Rocket Engineering, Jet Engine Engineering and Thermodynamics (undergraduate school).

Chihiro Inoue, Yu Ichiro Izato, Atsumi Miyake, Emmanuel Villermaux, Direct Self-Sustained Fragmentation Cascade of Reactive Droplets, Physical Review Letters, 10.1103/PhysRevLett.118.074502, 118, 7, 2017.02, A traditional hand-held firework generates light streaks similar to branched pine needles, with ever smaller ramifications. These streaks are the trajectories of incandescent reactive liquid droplets bursting from a melted powder. We have uncovered the detailed sequence of events, which involve a chemical reaction with the oxygen of air, thermal decomposition of metastable compounds in the melt, gas bubble nucleation and bursting, liquid ligaments and droplets formation, all occurring in a sequential fashion. We have also evidenced a rare instance in nature of a spontaneous fragmentation process involving a direct cascade from big to smaller droplets. Here, the self-sustained direct cascade is shown to proceed over up to eight generations, with well-defined time and length scales, thus answering a century old question, and enriching, with a new example, the phenomenology of comminution..
