Retraction and freezing of a water film on ice
Virgile Thiévenaz, Christophe Josserand, Thomas Séon
Abstract
A water drop impacts a cold surface, spreads and then retracts while simultaneously freezing. Experiments explain the surprising shape of the frozen drop and measure the contact angle dynamics of water on ice, by examining the competition between freezing and retraction.
