Visualization of droplet boiling on heated transparent solid surfaces with various thermal properties.
The purpose of the research described in this paper is to elucidate the phenomenon of miniaturization boiling, which involves the scatter of a large number of minute liquid particles from a droplet surface to the atmosphere when the droplet impinges on a solid heating surface. This behavior was photographed from the underside of the heating surface, with special attention to the liquid-solid contact. Transparent solid surfaces with various thermal properties included sapphire, glass with indium tin oxide coating, quartz, and quartz with chromium coating.
