Almost-sure enhanced dissipation and uniform-in-diffusivity exponential mixing for advection-diffusion by stochastic Navier-Stokes

Jacob Bedrossian, Alex Blumenthal, Samuel Punshon-Smith

We study the mixing and dissipation properties of the advection-diffusion equation with diffusivity and advection by a class of random velocity fields on …

The Batchelor spectrum of passive scalar turbulence in stochastic fluid mechanics at fixed Reynolds number

Jacob Bedrossian, Alex Blumenthal, Sam Punshon-Smith

In 1959, Batchelor predicted that the stationary statistics of passive scalars advected in fluids with small diffusivity should display a power spectrum along an ine…

Inviscid damping and enhanced dissipation of the boundary layer for 2D Navier-Stokes linearized around Couette flow in a channel

Jacob Bedrossian, Siming He

We study the 2D Navier-Stokes equations linearized around the Couette flow in the periodic channel with no-slip boundary conditions in the vanis…

Almost-sure exponential mixing of passive scalars by the stochastic Navier-Stokes equations

Jacob Bedrossian, Alex Blumenthal, Samuel Punshon-Smith

We deduce almost-sure exponentially fast mixing of passive scalars advected by solutions of the stochastically-forced 2D Navier-Stokes equations and 3D hyper-viscous Navier-Stokes…

Sufficient conditions for dual cascade flux laws in the stochastic 2d Navier-Stokes equations

Jacob Bedrossian, Michele Coti Zelati, Sam Punshon-Smith +1

We provide sufficient conditions for mathematically rigorous proofs of the third order universal laws capturing the energy flux to large scales and enstrophy flux to small scales f…
