Forward self-similar solutions to the 2D Navier--Stokes equations

Dallas Albritton, Julien Guillod, Mikhail Korobkov +1

We construct self-similar solutions to the 2D Navier--Stokes equations evolving from arbitrarily large --homogeneous initial data and present numerical evidence for their non-u…

Hyperbolicity of a semi-Lagrangian formulation of the hydrostatic free-surface Euler system

Bernard Di Martino, Chourouk El Hassanieh, Edwige Godlewski +2

By a semi-Lagrangian change of coordinates, the hydrostatic Euler equations describing free-surface sheared flows is rewritten as a system of quasilinear equations, where stability…

Long-time behavior of the Stokes-transport system in a channel

Anne-Laure Dalibard, Julien Guillod, Antoine Leblond

We consider here a two-dimensional incompressible fluid in a periodic channel, whose density is advected by pure transport, and whose velocity is given by the Stokes equation with…

Existence and uniqueness for plane stationary Navier-Stokes flows with compactly supported force

Julien Guillod, Mikhail Korobkov, Xiao Ren

We study the stationary Navier--Stokes equations in the whole plane with a compactly supported force term and with a prescribed constant spatial limit. Prior to this work, existenc…

Nonlinear stability at the Eckhaus boundary

Julien Guillod, Guido Schneider, Peter Wittwer +1

The real Ginzburg-Landau equation possesses a family of spatially periodic equilibria. If the wave number of an equilibrium is strictly below the so called Eckhaus boundary the equ…

Existence and uniqueness of steady weak solutions to the Navier-Stokes equations in

Julien Guillod, Peter Wittwer

The existence of weak solutions to the stationary Navier-Stokes equations in the whole plane is proven. This particular geometry was the only case left open since th…

Steady solutions of the Navier-Stokes equations in the plane

Julien Guillod

This study is devoted to the incompressible and stationary Navier-Stokes equations in two-dimensional unbounded domains. First, the main results on the construction of the weak sol…

Optimal asymptotic behavior of the vorticity of a viscous flow past a two-dimensional body

Julien Guillod, Peter Wittwer

The asymptotic behavior of the vorticity for the steady incompressible Navier-Stokes equations in a two-dimensional exterior domain is described in the case where the velocity at i…
