Abstract
The data of a ballistic experiment are analyzed, in which an intense capillary wave injects up microdroplets formed and levitated above a heated region of water due to an ascending convective steam-air flow. The drag force resisting the movement of a droplet is estimated. Using various theoretical approaches, the flow parameters (velocity at different heights, the rate of change of velocity) are estimated. The maximum size of droplets that can levitate freely has been determined. The impossibility of the stationary droplet levitation in a linearly inhomogeneous flow is shown.
