We used the basic two experimental methods to
understand the Film Boiling Heat Transfer; quenching and leidenfrost
experiment. The major points able to achieve are below,

1) Efficient core-cooling
strategy under the severe accident of nuclear power plant

2) Phenomenological investigation during phase-change on the modulated heat
transfer surface under high temperature condition

3) Development of technical methodology to identify the phase-change motion
at the film boiling heat transfer(droplet or liquid-vapor interface
motion)
