Vortex structures were also observed by Theissen  on a more realistic vehicle and were considered responsible for a delay in the aerodynamics of the wake flow
Wind impinging on a building creates zones of variable pressures on the building faces and also generates complicated wake flow patterns around the building.
Wind pressures are typically positive (acting into the building) on the windward face, and negative (suction, acting away from the building) on the sides, roof, and leeward face of the building where wake flows are present.
structure around external rear view mirror has been studied extensively.
To avoid the influence of wake flow
formed by temperature detection part, a heat insulation sub in velocity detection part is designed.
This indicates that the wake flow
speeds for Configuration II, with mid-skirts, are higher in the underbody region.
The similarities between the two sets of tomographic results, Figure 9a-d, indicates that while the grid resolution is relatively low with high overlap in the processing stage, there appear to be no issues resolving the internal wake flow
structures with the lower seeding densities experienced with the 30m/s tomographic data.
To solve this, simultaneous multi-camera stereoscopic-PIV that can measure enough size for the wake flow
The operation of AGS not only manages the amount of cooling airflow through the grille openings but also affects underbody, wheel arch, and wheel wake flows
to name a few.
