高温流れ場内における微小液滴の蒸発挙動の観測

抄録

It is well known that the Leidenfrost phenomenon occurs when a droplet approaches a hot surface. In our laboratory, targeting droplets of several micrometers size, a system for directly observation of the droplets flying in a high-temperature field have been developed and the analysis of the behavior of such small droplets in the Leidenfrost state have been focused. In this presentation, the problems and improvement of the equipment which is a home-made will be reported. Also, observation results of D.I. water and methanol droplets will be announce. For reference, in general, the droplets of methanol evaporated faster than that of D.I water, because it have a lower boiling points than water, even for minute droplets. which has a lower boiling point than that of water it was confirmed that methanol, which has a lower boiling point than that of water, evaporates faster than D.I. water.
