Separation dynamics of binary liquid mixtures – Theory & Experiment

Truman P., Varnik F., Uhlmann P., Stamm M., Raabe D., Institute of Polymer Research, DE

We study how chemically patterned surfaces can be applied for the separation of two incompatible liquids and introduce a novel simplified separation scheme utilizing surfaces with an abrupt change of surface energy. Firstly we analyse [...]

Chaotic flows in microchannels: A lattice Boltzmann study

Varnik F., Raabe D., Max-Planck Institut fuer Eisenforschung, DE

Lubricant flows are usually assumed to be laminar and the lubricatedmetallic surfaces are anticipated to be perfectly flat and references therein). Both assumptions are incorrectwhen it comes to a detailed analysis. Indeed, metallic surfaces arenever [...]
