Brinkmann Model and Double Penalization Method for the flow around a Porous Thin Layer ,
Résumé
in this paper we study a penalization method used to compute the flow of a viscous fluid around a thin layer of porous material. Using a BKW method, we perform an asymptotic expansion of the solution when a little parameter, measuring the thickness of the thin layer and the inverse of the penalization coefficient, tends to zero. We compare then this numerical method with a Brinkman model for the ow around a porous thin layer.
