CFD Analysis Of Underbody Wall Shear Stress On The Corvette Aerodynamic Package
The wall shear stress distribution on the vehicle's underside provides insight into boundary layer behavior andflow attachment. Regions of elevated wall shear indicate strong momentum exchange near the surface,corresponding to attached flow with effective energy recovery and pressure control.
Conversely, areas exhibiting low wall shear denote local flow separation or recirculation zones, where boundarylayer detachment reduces surface loading efficiency. The spatial extent and intensity of these low-shearregions directly correlate with underbody performance losses and diffuser effectiveness.
