Exponential mixing and enhanced dissipation on the unit sphere with Rossby-Haurwitz flows

Augusto Del Zotto, Marc Nualart

We exhibit a family of smooth incompressible velocity fields on the two-dimensional unit sphere such that the time evolution of any mean-free initial data passively advected by any…

Enhanced Dissipation and Transition Threshold for the Poiseuille Flow in a Periodic Strip

Augusto Del Zotto

We consider the solution to the 2D Navier-Stokes equations around the Poiseuille flow $(y^{2}, 0)$ on $T \times R$ with small viscosity $ν > 0$ . Via a hypocoercivity arg…
