Aerodynamic Study on the Vehicle Shape Parameters with Respect to Ground Simulation

Chenyi Zhang analyzes the influences of moving ground simulation technique in wind tunnel tests. In his work, the classical investigations on vehicle shape parameters with fixed ground conditions are reviewed with modern moving ground simulation technique. The investigations are performed by means of CFD simulations and model scale wind tunnel tests at IFS, University of Stuttgart. The shape parameters of two reference vehicles the DrivAer and the AeroSUV model with notchback, fastback and estate back are varied and investigated. The author presents different results in drag and lift for the varied geometry parameters. The classical results of the parametric study on the vehicle basic shapes for vehicle aerodynamics could be complemented with the findings of the present research.
