    Singularities at soft elastic interfaces

    Guest talk by Prof. Jacco Snoeijer (University of Twente)

    Soft elastic interfaces exhibit intriguing similarities to liquid interfaces: they possess a surface tension and are susceptible to interfacial instabilities. The first part of this talk addresses wetting on such very soft substrates. It is shown that „soft wetting“ fundamentally differs from the usual wetting on rigid surfaces. In the second part we discuss the formation of cusps and creases at elastic interfaces — and point out striking similarities with viscous cusps at liquid interfaces.

    Bringing coating and printing science alive with apps

    Guest talk by Prof Steven Abbott

    For those who need scientific solutions to their printing, coating or wetting problems help can be just an app away, with live demos covering, (de)wetting, (forced) drop spreading, dynamic surface tension, levelling, inkjet, evaporation and more. In his talk Prof Abbott will show that a large collection of free, easy-to-use apps covering many aspects of coating/printing makes it possible for the science to be used by everyone.

    Towards a Rigorous Analysis of Basic Contact Line Models

    Talk by Dr. Matthias Köhne (HHU Düsseldorf, Applied Analysis)

    The aim of this talk is to discuss basic models for contact line dynamics and, in particular, their principal linearizations and similar parabolic and Stokes type equations in prototype domains. We discuss the solvability of these prototype problems and, in particular, the existence of smooth solutions as far as this is actually known.

    Redefining Boiling Phenomena – New understanding of the heat transfer mechanisms during pool and flow boiling

    Prof. Satish G. Kandlikar (RIT)

    Talk by Satish G. Kandlikar (Rochester Institute of Technology, NY)

    Prof. Satish Kandlikar will give a talk on recently identified mechanisms which have beeen exploited to provide a new level of boiling heat transfer enhancement. Prof. Kandlikar's recent work on pool and flow boiling has provided a mechanistic understanding of the boiling phenomena at microscale and produced enhancement structures dissipating exceptionally high heat fluxes along with very high heat transfer coefficients.

    When surfaces matter: using nano-scaled surface features to control macro-scale transport

    Vortrag von Gary Rosengarten (RMIT University)

    Typical heat transfer correlations or surface property data assume that surfaces are smooth, or that they don’t effect transport properties such as convection or even radiation. However, nano-scaled features can have a massive effect on many transport properties- particularly those with free surfaces.
