Particle-pattern formation in incompressible periodic flows
Prof. Dr. Hendrik C. Kuhlmann, Institut für Strömungsmechanik und Wärmeübertragung
Experiments have shown that small particles suspended into a confined liquid can exhibit a rapid and nearly complete de-mixing. Depending on the underlying incompressible flow the particles may arrange themselves into dynamic, one-dimensional, thread-like accumulation structures. By modeling and numerical simulation we show that the de-mixing is primarily caused by repeated particle-wall collisions of finite-size particles, while inertial effects are of lesser importance.
