Abstract

In collaboration with the University of Stuttgart and the Research Association of Automotive Technology (FAT), a series of on-road [1] and wind tunnel experiments [2] were conducted in order to characterize the onflow conditions for a vehicle driving behind another vehicle under real-world conditions. In conjunction with these experiments a CFD study was undertaken for both the on-road and wind tunnel measurements. This study, the subject of the paper, assesses the ability of two different CFD approaches to reproduce both the observed on-flow conditions as well as the aerodynamic drag of the vehicle. Both sets of CFD calculations are performed within the framework of the OpenFOAM [3] computational library.
