循環型空気再生システムにおける混相流に関する課題

Development of closed-loop air revitalization producing oxygen (O₂) from carbon dioxide (CO₂) exhaled by astronauts is required for future manned space missions. This paper shows recent research on two of three subsystems of a closed-loop air revitalization system: water generation form CO₂ reduction and water electrolysis to provide O₂. Practical large-scale tests of CO₂ reduction and water electrolysis showed that various gas-liquid two-phase conditions in a reactor would be important to establish systems operated under microgravity.
