Icing of solid surfaces is an ever-present problem for many engineering applications. In particular ice accretion due to the impact and freezing of supercooled water drops is rich in various physical processes and of relevance for aviation, road traffic, shipping, wind turbines, and high-voltage power lines and insulators. It is initiated by the impact of water drops being in a thermodynamic meta-stable state, followed by nucleation of the impacting drops and ending up with solidification of the liquid, potentially influenced by the impact surface. All of these processes have been separately the focus of extensive experimental, theoretical and numerical studies for many decades. However, for the first time Markus Schremb's dissertation attempts to consolidate the understanding of all involved mechanisms, and to examine them in the context of icing of surfaces.

The European Research Community on Flow, Turbulence and Combustion (ERCOFTAC) is a scientific association in the fields of fluid mechanics, turbulence and combustion research. The annual da Vinci Competition is one of the most important events in ERCOFTAC’s calendar. Its importance arises from the fact that it is the principal ERCOFTAC forum for the youngest, most gifted researchers in our field in Europe to present the products of their endeavours.
