摘要:
Evaporation of a heated sessile water drop was studied experimentally at a temperature difference between the substrate and surrounding atmosphere from 30 to 60 degrees C. The studies were performed on the substrates with micro- and nanocoatings with different wettability. The features of evaporation were studied for the pinned, partially pinned and depinned contact line (solid-liquid-gas interface). It is found that during the evaporation process the specific evaporation rate (mass loss per unit of the drop surface area) increases, particularly at the last stage of the drop lifetime.
