Outline of Final Research Achievements |
To investigate the interaction between liquid film and droplet in an annular-mist flow, high-speed liquid film sensing method with an electrical conductance measuring system and a multi-electrode sensor was developed. The air-water two-phase flow in a narrow vertical channel was measured by the liquid film sensor and high frame rate neutron radiography simultaneously, and the two-phase flow structure could be measured. In addition, a liquid film flow simulation with volume-of-fluid method was performed and the possibility of the database construction for liquid film and droplet behaviors was shown.
