Inertia, Turbulence and the Concentration Field in Active Fluids

Explore the fascinating world of active fluids in this Rothschild Public Lecture by Professor Sriram Ramaswamy from the Indian Institute of Science. Delve into the interplay between broken time-reversal symmetry and conservation laws of matter and total momentum in self-driven particle fluids. Examine the transition from order to active turbulence, focusing on an inertial perspective rather than a viscous one. Investigate simplified models of one-component active fluids and densely packed suspensions. Discover the interactions between hydrodynamic flow and particle currents in various settings, including obstacles in dilute suspensions and phenomena in denser systems. Gain insights into fundamental theoretical issues surrounding active fluids and their behavior. This lecture, part of the Anti-diffusive dynamics program at the Isaac Newton Institute for Mathematical Sciences, offers a comprehensive exploration of inertia, turbulence, and concentration fields in active fluid dynamics.
