Benjamin West B Room
Wetting processes involve subtle interaction between microscopic physics at the contact line and the bulk properties of the liquid film. Such problems are important in fields ranging from microchip fabrication to de-icing of airplane wings. The difficulty in modeling such problems can be seen at the level of a fundamental paradox in which the no slip boundary condition at the fluid/solid interface introduces an inifinite energy dissipation at a moving contact line. Various techniques have been considered to resolve the inconsistency, including introducing slippage along the liquid/solid interface, incorporating Van der Waals forces into the model, and introducing molecular dynamics interactions on a sub-continuum scale. Our challenge is to develop models that accurately predict a wide range of phenomena including complete, partial, and non-wetting behavior, changes in surface tension, evaporation of the film, and external forcing. This minisimposium draws from the mathematical, physical, and engineering communities to address modelling techniques, their mathematical validity, and their agreement with experimental observation.
