Dr. Giuseppe Pucci
CNR, University of Calabria (Italy)
“Capillary surfers at a vibrating fluid interface”
I am a researcher in physics at the National Research Council of Italy (CNR), based at the Department of Physics of the University of Calabria, Italy. Previously, I worked at the Institut de Physique de Rennes (France), Brown University (USA), Massachusetts Institute of Technology (USA), Università della Calabria (Italy), and Université Paris Diderot (France). My research focuses on phenomena at fluid interfaces with the aim of contributing to the fields of fundamental fluid dynamics, active complex systems, and quantum foundations, the latter by developing classical analogues of quantum phenomena. My research occasionally touches on physics teaching, soft matter, and applied physics. I am fascinated by the possibility of exploring fundamental questions in physics by working on tabletop experiments. My research approach thus combines relatively low-cost experimental physics with theoretical modeling, and benefits from continuous collaboration with theorists. (www.gpucci.net)

Dr Guillaume Castanet
LEMTA CNRS, Nancy (France)
“Heat and Mass Transfers in Droplet Flows: Recent Advances Using Laser-Induced Fluorescence”
Guillaume Castanet is a research scientist of the French National Centre for Scientific Research (CNRS). He received his PhD degree in Mechanical engineering from the University of Lorraine (Nancy, France) in 2004. Then, he was appointed as postdoctoral fellow for two years at the Technical University of Darmstadt, Germany, where he conducted research activities on the evaporation and the drying of droplets containing solid particles in suspension. Since 2006, Guillaume Castanet has been working in the Laboratory of Energies Theoretical and Applied Mechanics (LEMTA) at the University of Lorraine. His research activities concern heat and mass transfer phenomena in droplet-laden flows and thin liquid films. They address topics such as droplet impact on heating surfaces in relation to spray cooling applications, icing of subcooled droplets, anti-icing systems, heat transfer enhancement in wavy thin liquid films, puffing/micro-explosion of water-in-oil composite droplets, heating and evaporation of closely spaced interacting droplets… Experiments are conducted on several flow configurations: single drops, monodisperse droplet streams, sprays and falling liquid films. A special research interest is focused on the development of non-intrusive optical measurement techniques to characterize heat and mass transfers. However, light scattering at complex liquid/gas and liquid/solid interfaces pose serious challenges for optical measurement techniques. Innovative techniques based on laser-induced fluorescence, are developed using either the intensity of the fluorescence signal or the fluorescence lifetime. They aim at achieving time and space resolved measurements of temperature and chemical composition inside moving and deforming droplets and liquid thin films. The combination of several measurement techniques allows to get an understanding of the couplings between heat and mass transfers, hydrodynamics, and phase changes (evaporation, solidification...). Guillaume Castanet has published more than 100 papers in journals and conferences proceedings. He is currently a member of the ILASS-Europe committee to promote the science and application of Liquid Atomization and Spray Systems.
