On propose une version hybride de la méthode Fast-VPP en écoulement dilatable : variables colocalisées et projection décalée. On précise les conditions nécessaires à son application efficace. Des résultats numériques illustrent le gain en effort de calcul pour l'obtention de régimes stationnaires.

We propose a hybrid version of the Fast VPP method for dilatable fluids: collocated variables/staggered projection. The necessary conditions for its effective application are outlined. Numerical results illustrate the significant computation-cost reduction to reach stationary regimes.
