Inertial particles in turbulence : preferential concentration and settling velocity
Turbulent flows laden with inertial particles occur in many industrial and environmental situations (pollutant dispersion, plankton, engine optimization…) During the last forty years, many properties of these flows have been evidenced, nevertheless, a model equation describing them is still out of reach, particularly regarding the back reaction of the particles on the carrier fluid or regarding the possible collective effects on the particles dynamics.
We show experimental and numerical results on the strong heterogeneities appearing in the concentration fields and try to identify possible collective effects leading to the existence of clusters that can live for times long compared to the large turbulent scales. We also review the various tools used to evidence and quantify preferential concentration.
The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
