Study of the influence of different parameters on the flight of microdroples over the contact line in a liquid film heated from below

Abstract

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.
