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.
