Abstract

This paper presents an experimental study of evaporation of a millimeter-sized sessile water droplet into open atmosphere in a wide range of the temperature difference (from 0 to 76 K) between the solid substrate and the atmosphere. The study was performed using two substrates made of copper. One of them had no coating and was polished to the root mean square roughness of about 20 nm. Another one was coated with a micrometer-thick film of single-walled carbon nanotubes. With the help of precise drop shape analysis system, the mode of droplet evaporation with pinned contact line was studied. No appreciable difference was detected in evaporation droplet dynamics between the two substrates for the substrate temperatures from 24 to 100 °C.
