Levitation of microdroplets above an evaporating layer of water

\nThe paper investigates a levitating array of microdroplets above a heated layer of distilled degassed water with an area of 40×40 mm2. The droplets are distributed unevenly, and most of them accumulate at the edges of the test section. The coalescence of droplets with the liquid layer is studied. It is shown that with increasing liquid layer temperature, the average diameter of the coalescing microdroplets increases.\n
