Seminar Cancelled:How Hydrodynamics and Thermodynamics Control Ice Accretion by Impacting Drops of Supercooled Water
Markus Schremb

Details:

Icing of solid structures is a phenomenon present in various fields of nature and technology. Frost flowers growing on surfaces, the shape of snow flakes or trees covered in hoar frost on a sunny winter day are the more fascinating and beautiful facets of this phenomenon. However, ice accretion on engineering structures may cause severe problems for the respective system and is a hazard for aircraft, ships, road traffic and power supply systems. It may cause crashes of aircraft, capsizing of ships, severe traffic accidents, or the malfunction and collapse of transmission lines and pylons of power supply systems. To reduce the risks of ice accretion and promote the design of anti-icing surfaces, a deep understanding of the fundamental mechanisms taking place during ice accretion is of utmost importance. Different hydrodynamic and thermodynamic processes, such as drop impact, conjugate heat transfer, ice nucleation and freezing, take place during icing due to the impact of supercooled water drops, and may mutually influence each other during the complex process. In order to shed further light on the processes involved in ice accretion, current results concerning selected sub-processes are presented.
