Airflow over the Ahmed body is simulated by means of the Embedded LES technique. This is a zonal approach which allows the LES turbulence model to be used in a sub-domain while the rest of the domain is solved using a RANS turbulence model, i.e., the k\u03c9-SST model. This allows the LES zone to be restricted to the rear end of the vehicle where the unsteadiness of the flow must be accurately predicted. A comparison with full RANS modeling and experiments is reported.
