| Outline of Final Research Achievements |
The objectives of this study is to clarify the phase change thermal flow of vapor bubble in microchannel by numerical simulation. Additionally, to investigate the evaporation of liquid film on the solid surface, near-wall evaporation phenomena in convective boiling was evaluated by using contact line evaporation model.
The numerical simulation of expansion process of vapor bubble in isothermal microchannel was conducted. By calculating the shape of liquid-vapor interface and heat flux distribution on the isothermal wall, the length of heat flux distribution was shorter than the length of vapor bubble. Additionally, the numerical simulation on convective boiling heat transfer with contact line evaporation model was also conducted. In a single bubble growth in convective boiling, the contributions of contact line evaporation and convective heat transfer were different in the front and back side of vapor bubble.
