DY 17: Focus: Droplets (joint session DY/CPP)

Montag, 12. März 2018, 15:30–19:15, BH-N 334

The physics of droplets is surprisingly rich - and full of surprises. This holds for droplets in ambient gas and for droplets in other liquids. The geometric and dynamical parameters which enter are size and velocity and the material properties are density, surface tension, velocity, volatility, freezing and melting points, latent heat, viscosity, thermal conductivity,... and all this holds for both the drops and for the surrounding gas or liquid. Moreover, both droplet and surrounding can be multicomponent and phase transitions and chemical reactions. The consequence of this huge parameter space is a plethora of often very surprising phenomena - and many are technologically very important. The systematic optimization of processes involving such phenomena needs a fundamental understanding of the physics. In this session various examples are given in which the community has worked towards such an understanding, combining controlled experiments, numerical simulations, and theoretical analysis.
