L'objectif de cette étude est de minimiser, par rotationsinusoïdale, le coefficient de traînée moyen d'un cylindrecirculaire en régime laminaire. Une procédure d'optimisationcouplant modèle réduit par POD et méthode à région de confiance(TRPOD) est utilisée. Cette approche conduit à une réduction ducoefficient de traînée de 30 % pour un coût de calcul limité.
