Flow Regimes, Transitions and Segregation in Granular and Particle-laden Flows


we have been made aware of a very convincing phone scam that is focusing on our workshop participants. Participants may be contacted by phone by a firm called Business Travel Management to arrange accommodation for workshops and/or programmes.  This includes a request to enter credit card information.

Workshop Theme

There are a broad range of flow regimes in both granular and particle-laden flows, ranging through solid, fluid and gas-like behaviour. Mathematical models are now having some success at predicting the behaviour in particular flow regimes. However, even in elementary flow situations, all three phases may be active in different regions of the flow. This significantly complicates the formulation and solution of flow problems. This conference will provide a forum for mathematicians, engineers, and physicists to discuss the latest mathematical theories and experiments for the different flow regimes and transitions between them. Particle segregation due to differences in size and/or other particle properties will also be considered. This is of fundamental importance for mixing and de-mixing in many industrial processes and natural flows. Yet despite half a century of research, the mechanisms of segregation are not well understood. This meeting will seek to characterize the fundamental physical processes at work, and improve their description in both theoretical and computational models.
