| Abstract: | This paper presents an experimental study of microscopic explosive boiling introduced by a pulsed laser. The violent explosive
boiling was observed in the liquid film, and the vapor bubbles together with liquid droplets were expelled from the platinum
film. It is found that the apparent bubble nucleation temperature is a strong function of the heating rate. The pressure signal
appears as continuous oscillation and is intensified as laser power density increases. |
