Large-Eddy Simulation of the Flow Around a Ground Vehicle Body
Artikel i vetenskaplig tidskrift, 2001

Large Eddy Simulation of the the flow around bus-like ground vehicle body is presented. Both the time-averaged and instantaneous aspects of this flow are studied. Time-averaged velocity profiles are computed and compared with the experiments by Duell and George (SAE Paper 1999-01-0812) and show good agreement. The separation length and the base pressure coefficient are presented. The predicted pumping process in the near wake occurs with a Strouhal number St=0.073, compared with St=0.069 in the experiment. Unsteady results at two points are presented and compared with the experiments. The coherent structures are studied and show good agreement with the experiments.
