Thickness measurement in a horizontal liquid layer when heated from a localized hot-spot

Abstract

Thermocapillary breakdown of thin (0.3 - 0.7 mm) horizontal layers of liquid (ethanol) when heated from a localized hot spot was investigated experimentally. The effect of layer thickness on the breakdown dynamics was studied. Visualization and control of the liquid layer were carried out using schlieren and confocal techniques. Main steps of the breakdown process were determined with the help of both systems. Evolution of the layer thickness in the center of substrate was observed and the critical thickness of the layer was measured using confocal sensor.
