Abstract

Two holographic gratings are used as beam splitting elements to form a special shearing interferometer through which time changing profiles of liquid drops evaporating on transparent flat plates are visualized and measured in real time. Binary liquids with various mixture ratios have been tested. Characteristics of thermal stability in binary droplet vaporization are revealed from the sequential changes of interference patterns. An interfacial flow map for binary drops is constructed that defines the domains of stable and unstable type evaporations.
