ADIW01 - Layering — A structure formation mechanism in oceans, atmospheres, active fluids and plasmas

The incompressible Toner-Tu (ITT) equations are one of the commonest flocking models in the area of active matter. They possess certain invariance properties which lead to an intriguing correspondence with both the Navier-Stokes equations (NSEs) and the multifractal turbulence model of Parisi and Frisch (1985). In this talk we will display a variety of both 2D and 3D computations of the ITT equations performed in collaboration with Kiran, Padhan and Pandit: see Physica D, vol 444, 133594 (2023).
