| Abstract: | The experiment of rapid transient explosive boiling was studied under low temperature environment, a high-power pluse laser as the source of heat, platinum thin film with high response and precision as both the measuring temperature and heated element. Boiling process under different condition were taken pictures depending on the use of microscopy in order to find how system variables such as surface condition, laser parameters effect the rapid transient explosive boiling under low temperature environment. |
