Fig. 2. Depiction of the vehicle dataset consisting of sport utility vehicles (SUV), hatchbacks, sedans, and box geometries.
a Representative voxelized vehicle geometries for different car types. b Example 3D and 2D (center plane) isocontours of normalized total pressure coefficient, Cp,t, for different car types. Cp,t = 0 isocontour is shown, indicating separated flow. c Probability density plot, p(CD), of normalized drag coefficient, CD, with respect to vehicle type.
