Dépouillement assisté par ordinateur des visualisations pariétales en aérodynamique (A computer-assisted analysis technique for parietal visualization understanding)

The experimental techniques for analysis of three-dimensional separated flows for vehicles are sometimes insufficient when a detailed study of the production of vortical structures in the wake is required. The parietal visualization technique is commonly used in automotive aerodynamics but, in this industrial context, the correct reading and interpretation of the images is often difficult and expensive. The aim of this study is to present a simple numerical interactive technique which would give the experimenter a quick validation of his visual analysis.
