Une méthode de collocation utilisant l'approximation diffuse est utilisée pour étudier l'écoulement autour d'obstacles. Après une validation pour le cas d'un cylindre de section circulaire, nous montrons que la méthode permet d'obtenir le nombre de Strouhal pour un objet cylindrique de section semi-circulaire au nombre de Reynolds de 65.
A diffuse approximation based collocation method is used for the study of the flow over a half-circular cylinder. We give some results on the instationary wake at a Reynolds number Re=65.
