Bounce-Back Boundary Condition at First Order
Prof. Francois Dubois
University Paris-Sud, France

We first recall our analysis of the bounce-back boundary condition based on an asymptotic singular expansion as the mesh size tends to zero. Then it is natural to extend the previous work at first order and a natural extension of the previous analysis is straightforward. As a consequence, we propose a boundary condition able to capture exactly quadratic velocity profiles without any need of "quartic" relaxation parameters.
