Abstract: Turbulent flows are ubiquitous. They are central to natural processes from the depths of the oceans to the heights of our atmosphere, and beyond. And yet, turbulence remains one of the great unresolved problems in classical physics. But what does this statement really mean? In this lecture we will discuss what this may mean and its importance not just in macroscopic, inanimate matter but also how it shows up in "living" fluids.
About the Speaker: Samriddhi Sankar Ray is an Associate Professor at the International Center for Theoretical Sciences of the Tata Institute of Fundamental Research (ICTS-TIFR), in Bangalore. As a statistical physicist, his areas of interest include different aspects of turbulent flows and turbulent transport. These include turbulent transport of finite-sized particles, Lagrangian measurements, questions related to intermittency.
