We study thermo-fluid dynamics in jet engines, rocket engines, and satellite engines. Experiments such as high-speed visualization are combined with numerical simulation and theoretical modeling to analyze the internal phenomena, and the new knowledge obtained is integrated to predict and optimize not only the performance indices of actual engines but also the heat transfer.
We are also interested in fragmentation and phase change of liquid metal in order to produce high-quality metal powder, which is important for manufacturing aerospace engines and automobile ones.
In addition, our research field covers the physics in everyday life such as water drops, sparks, and fireworks, to elucidate their mysteries hidden for centuries applicable to engineering techniques.
