To allow for a large variety of investigations, the DrivAer body was developed as a modular concept with 18 different Mock Up configurations.
Different underbody configurations
Furthermore a configuration allowing engine bay flow has recently been added to allow even more close to reality test cases.
To describe the different configurations of the DrivAer model a simple categorizing system has been derived.
First Letter: describes the geometry of the top
E Estate Back
Second Group of Letters: describes the underbody geometry
D Detailled Underbody
S Smooth Underbody
EB Engine Bay Flow
Third Group of Letters: describes the configuration of the mirrors
wM with Mirrors
woM without Mirrors
Fourth Group of Letters: describes the configuration of the wheels
wW with Wheels
woW without Wheels
Fifth Group of Letters: describes cooler configuration (optional for engine bay flow)
wL with Leakage around the Cooler
woL without Leakage around the Cooler
Accordingly the abbreviation E_S_woM_wW describes the estate back configuration with a smooth underbody, without mirrors and with wheels.
To encourage independent experimental and numerical studies, the CAD data of the DrivAer model is available on request. The data is provided either in .IGES or in .STEP format.
