Abstract

The aim of this work is to fine-tuned a numerical procedure to predict the external aerodynamics flow around a real car. The hybrid RANS/LES method, called DDES, has been selected based on previous work and comparison between many turbulence approaches. First, the numerical procedure has been developed on the \(25^{\circ }\)Ahmed body. Based on this simplified geometry, we were able to define the numerical setup and grid in order to reproduce very accurately the flow around this shape. The second part of the work was to transpose this methodology on a more realistic vehicle, with some geometrical simplifications. At this preliminary stage of the study, the results are encouraging.
