报告摘要:Turbulence is everywhere on the earth as it is in the sky. I will present a guided tour across some of the most important open questions concerning the role played by turbulence in modern fluid dynamics. I will address fundamental theoretical questions connected to the existence of -infinitely many- anomalous scaling exponents and applied ones, related to the formation of coherent energy-containing structures in atmospheric flows under rotation, with helicity or in strongly confined thick laters. The aim is to highlight what we do not know and what are the main mathematical, phenomenological, numerical and experimental obstacles that still make turbulence an unsolved problem of paradigmatic importance in, e.g., out-of-equilibrium statistical mechanics, mechanical engineer and atmospheric physics.

报告人简历:Prof. Luca Biferale received his Ph.D. in Anomalous Scaling Laws in Fully Developed Turbulence in University of Rome “La Sapienza” in 1993. From 2005-2014, he was an associate Professor of Theoretical Physics, Mathematical and numerical modelling in Dept. Physics, University of Rome “Tor Vergata” (Italy). Since 2014, he has been a full Professor of Theoretical Physics, Mathematical and Numerical modelling Dept. Physics, University of Rome “Tor Vergata” (Italy).
