SUMMARY:BurgersTour/ME lecture: Floating on Turbulence
DESCRIPTION:Speaker: prof. Filippo Coletti (ETH Zurich)\nHost: Niels Deen
 \n\nFrom marine litter to ice floes\, natural bodies of water are often p
 opulated with floating objects spanning vast ranges of size\, shape\, and
  concentration. Predicting their behaviour requires understanding how tur
 bulent water motion is altered by the presence of the free surface\, and 
 how the underlying turbulence influences the interfacial dynamics between
  the surface and the floating objects\, as well as among interacting floa
 ters. Even in the seemingly simple case where surface waves are negligibl
 e\, the problem is rich in fascinating phenomena.\nThis seminar presents 
 a series of experiments conducted in flow facilities large and small\, in
  which marginally buoyant particles (millimetric to centimetric\, round a
 nd irregular\, solid and deformable) float on turbulent water. For simpli
 city\, the focus is primarily on two opposite limits. First\, a dilute su
 spension of non-interacting discs significantly larger than the dissipati
 ve scales of turbulence is considered. These discs exhibit translational 
 and rotational motions dictated by the local flow\, coarse-grained at the
  scale of the particle. Second\, dense suspensions of smaller spherical p
 articles are considered. These form multiscale\, percolating clusters bou
 nd by capillary forces\, whose dynamics is well described by a population
 -balance framework. Finally\, the seminar provides insights into the prof
 oundly different behaviour exhibited by floating rods and oil droplets.\n
 Filippo Coletti is Professor of Experimental Fluid Dynamics at ETH Zurich
 \, where he has been since 2020. Previously\, he was McKnight Land-Grant 
 Professor of Aerospace Engineering and Mechanics at the University of Min
 nesota\, which he joined in 2014. He completed his doctoral studies at th
 e Von Karman Institute for Fluid Dynamics and the University of Stuttgart
 \, earning his PhD in 2010. He was subsequently a postdoctoral fellow at 
 Stanford University from 2011 to 2013. He received the CAREER Award from 
 the U.S. National Science Foundation in 2015 and an ERC Consolidator Gran
 t from the European Research Council in 2022. He is a Fellow of the Ameri
 can Physical Society and an Associate Editor of the Journal of Fluid Mech
 anics. He founded and co-organizes the Fluid Mechanics Tour of the Alps\,
  an itinerant seminar series featuring leading researchers in fluid mecha
 nics. His research focuses on multiphase flows\, which he investigates us
 ing a wide range of experimental techniques\, with applications in enviro
 nmental\, biomedical\, and industrial systems.
