Abstract

We present an original study on the numerical stabiliy of explicit schemes solving the incompressible Euler equations on an open domain with slipping boundary conditions. Relying on the skewness property of the non-linear term, we demonstrate that some explicit schemes are numerically stable for small perturbations under the condition δt≤ C δx^2r/(2r-1) where r is an integer, δt the time step and δx the space step.
