Artificial boundary conditions for stationary Navier-Stokes flows past bodies in the half-plane
Christoph Boeckle, Peter Wittwer
We discuss artificial boundary conditions for stationary Navier-Stokes flows past bodies in the half-plane, for a range of low Reynolds numbers. When truncating the half-plane to a…

On the existence of solutions to the planar exterior Navier Stokes system
Matthieu Hillairet, Peter Wittwer
We consider the stationary incompressible Navier Stokes equation in the exterior of a disk B with non-zero Dirichlet boundary conditions on the disk and zero boundary conditions at…

Some exact results for Boltzmann's annihilation dynamics
Francois Coppex, Michel Droz, Jaroslaw Piasecki +2
The problem of ballistic annihilation for a spatially homogeneous system is revisited within Boltzmann's kinetic theory in two and three dimensions. Exact analytical results are de…
