Vorticity Leray-α model for Navier-Stokes equations with viscosity depending on the distance to the wall
Résumé
We introduce a vorticity Leray-α model with eddy viscosity depending on d(x, ∂Ω) η where ∂Ω is the boundary of the domain and η ∈]0; 1[. We prove that this system admits fairly regular weak solutions converging when α goes to 0 to the solution of a reference system.
