Fluids and fluid flows are everywhere and are key to a vast number of scientific problems and industrial applications. Fluid flows can display extremely different behavior depending on the length- and time-scale of observation, on the internal fluid structure, on the flow geometry and on the presence of (external) forces.
With the present course we will offer to PhD students and to young researchers the possibility to have a rather complete overview of the different type of behavior that fluids can exhibit under different flowing conditions. The course will cover from the dynamics of complex fluids to the statistical description of complex flows. In particular, the course will address the physics of yield stress materials, the rheology of dense fluid suspensions, the physics of laminar and turbulent flows, the (turbulent) transport of heat and mass. Lectures will present the phenomenology, the theoretical framework and where appropriate they will illustrate numerical and experimental approaches.
The organization of the course will combine the expertise of both JBMC and CISM and will address both the Dutch scientific community working on fluid mechanics as well as the international community (CISM).
