Summary:A code based on a vortex method for simulating viscous vortex flow around a circular cylinder has been developed. The original method to obtain the no-through and no-slip condition introduced here is described in detail. The diffusive part of the vorticity transport equation is treated using a deterministic method based on the solution of the heat equation. Results have been obtained and are presented concerning the vorticity field, the velocity field, the evolution of drag and lift coefficients and the Strouhal number. Un code de calcul d'écoulement tourbillonnaire de fluide visqueux autour d'un cylindre, fondé sur une méthode particulaire a été développé. La méthode originale d'obtention de la condition d'adhérence mise en place ici est décrite en détail. Le traitement de la partie diffusive de l'équation de transport de la vorticité utilise, lui, une méthode déterministe fondée sur la solution de l'équation de la chaleur. Les résultats sont présentés pour l'évolution du champ de vorticité, du champ de vitesse, des efforts sur le profil et le nombre de Strouhal.
