The purpose of this work was to study the levitation of microdroplets of water condensate (about 10 μm in size) above a liquid surface and above a dry surface in a wide range of experimental parameters (microdroplets of condensate levitate due to the Stefan flow). The assigned tasks were studied using experimental methods. It was found that with increasing substrate temperature, the rate of droplet condensation and the rate of droplet evaporation increases. The rate of droplet evaporation over a dry substrate is much higher than the rate of droplet condensation over a wetted surface. The dependences of the height of levitation to the center of the drop on the radius of the drop levitating above the liquid layer at different values of the substrate temperature were also studied.
