“…In [5], with the help of high-speed shooting, it was found that the cluster "disappears" in a time of about 3 ms as a result of the propagation of a capillary wave caused by the fall of one drop -the drop of the "initiator". In [6][7][8], it was experimentally established that infrared irradiation of a drop cluster levitating above the water surface reduces the rate of condensation growth of liquid microdroplets and the subsequent merging of the drop cluster with a water layer. As a result, irradiation can be used to stabilize levitating clusters for a long time.…”

In this work, experimental studies were carried out on the flight of levitating liquid microdrops over the contact line around a dry patch formed in the horizontal liquid film heated from below in the temperature range of 52°C - 77°C. The working area is a textolite base, in the center of which a copper rod of a circular cross section with a diameter of 3 mm is pressed. The copper rod serves as a heating element. It was found that with an increase in the substrate temperature and decrease in the diameter of the microdroplets the height of the flight increases.

“…At the outset of observations of levitated clusters, it was found that the droplet growth follows closely Maxwell's diameter-square law [30,31], meaning that the droplet area grows linearly with time. Later, a technology was developed to suppress condensational growth through the exposure to infrared radiation [32,33]. The dependence of the growth rate of droplets on their number in the cluster was studied in [34].…”

The condensational growth of spherical water microdroplets is studied in a laboratory setup and with a mathematical model. In the experiment, droplet clusters are kept in a freely levitated state within an upward-oriented flow of water vapor. In the presence of an electrostatic field of 1.5 • 10 5 V m -1 , droplet growth is accelerated by factors 1.5 to 2.0 as compared to conditions without any external electric field. Presumably water molecules in the ambient air are accelerated through the presence of the electric field. A kinetic model to predict the acceleration of condensational growth confirms this hypothesis to be feasible. The droplets themselves are polarized so that the deposition of steam molecules is facilitated in the electric field. The simplifications and limitations of the model are discussed.
