| Outline of Final Research Achievements |
To establish the technology of the propellant management for liquid rocket, the pressure drop in closed vessels were intensively investigated. In the experiment, heat and mass transfer indicated by the pressure change induced by sloshing in the model-scale tank driven by the mechanical exciter were successfully obtained. Compared with the visualized motion of liquid, the enhancement of hear transfer coupled with the non-linier motion had different order of magnitude from those in the cases with linier response. The magnitude of heat flux between two phases in sloshing was found to have strong correlation with the appearance of droplets and wavy surface.
Finally, non-isothermal sloshing of cryogenic fluid was investigated. Not only the motion of liquid nitrogen, but also the condensation of liquid nitrogen was successfully visualized. It was also confirmed that vapor-liquid coexistence system of single-component under non-isothermal condition was easy to change its pressure.
