[Category Ⅲ] Space Environmental Fluid Dynamics

Department of Earth System Science and Technology


Associate Professor Shuichi MATSUKIYO , Assistant Professor Shogo ISAYAMA,  
Labo Site

Space is filled with plasma. In our heliosphere the main source of plasma is the sun. Magnetospheres of planets are connected with the sun via the plasma filling the interplanetary space. Their behaviour is influenced in many ways by solar activity. The heliosphere itself is exposed to interstellar space which is also filled with interstellar plasma... We study a variety of space environments from near Earth to distant high energy objects. We also work to develop the propulsion techniques of spacecraft by controlling plasma.

Plasma and Quantum Science and Engineering


Associate Professor Kazunari Katayama , Assistant Professor Makoto Oya,  
Labo Site

With the aim of developing attractive next-generation energy systems, we are engaged in education and research in the fields of chemical engineering such as process engineering and thermal mass transfer engineering. Through fundamental experiments, we try to model chemical reactions and mass transfer phenomena, and then to use numerical simulations to pursue optimal systems. In the development area of ​​most advanced science and technology, there are many situations in which it is difficult to predict phenomena based on just conventional knowledge.In our laboratory, we are challenging to correctly understand and model mass transfer phenomena occuring in special environments such as the interface between plasma or supercritical CO2 and solid walls, the flow field of high-temperature melts (liquid metals and molten salts), and the field of nuclear transmutation reaction by neutrons. Additonally, we are also actively studying on the hydrogen production using solid electrolyte cell or plasma, and environmental dynamics of tritium, which is a radioactive hydrogen isotope. These scientific achievements will be useful for the realization of nuclear fusion reactors, next-generation fission reactors, and a society utilizing hydrogen energy and renewable energy.
