Abstract
The paper presents a short description of the model of the phenomenon of
droplet spreading in presence of a liquid film, as well as the
experimental facility, calculations methodology and results of
experimental research concerning determination of the boundary angle at
which droplet begins to slide on the horizontal or inclined surface of the
plate. Values of boundary angle have been applied to estimate the
microscopic dynamic advanced angle of the droplet on the flat surface in
presence of a liquid film.
