1 Characterization of the Near-Wake of an Ahmed Body Profile
Authors: Stéphanie Pellerin, Bérengére Podvin, Luc Pastur
Abstract:
In aerovehicles context, the flow around an Ahmed body profile is simulated using the velocity-vorticity formulation of the Navier-Stokes equations, associated to a penalization method for solids and Large Eddy Simulation for turbulence. The study focuses both on the ground influence on the flow and on the dissymetry of the wake, observed for a ground clearance greater than 10% of the body height H. Unsteady and mean flows are presented and analyzed. POD study completes the analysis and gives information on the most energetic structures of the flow.Keywords: Ahmed body, bi-stability, LES, near wake.
