Abstract

The paper presents experimental investigations into the process of spreading of a liquid droplet over the surface. The wall area covered by the droplet is characterized by a spreading ratio β_R. It has been confirmed that the value of β_R increases when the initial droplet volume increases and the droplet-wall-environment system is in the quasi-static state. However, the influence of the initial surface temperature on β_R has not been found.
