Comments:
The Ahmed Body has long been used as a standard test case for automotive external aerodynamics. It has been studied within the Models for Vehicle Aerodyamics (MOVA) European collaborative project. It was one of the test cases of the FLOMANIA EC project, and the geometry was used in an ERCOFTAC/IAHR workshop.
Please identify Underlying Flow Regimes for this AC:
1)BL separation from smooth surface under apg. 2) laminar-turbulent transition 3) forward face stagnation, 4)separated counter rotating vortices. 5) wakes

Comments:
8.1    The D30 contains a discussion on the comparison of test data and CFD. More information is provided in the paper by Florian Menter, which also include a variety of figures
8.2    Some minor discussion on accuracy of CFD results provided. Need to consult the source publications to judge whether or not this is supported by the results.
