WebJul 23, 2024 · So vortex generator does not modify the Reynolds number. However, it trips the flow aft of the device into turbulent flow. Turbulent flow, in fact, has higher drag than a laminar flow (at the same Re). Therefore, on top of the additional skin friction drag introduced by the VGs, the aerodynamic surface would also have higher drag. WebJan 16, 2024 · The intensity of the vortex will depend on the speed of the object. These vortices create a drag on the object. In the case of Formula 1 cars, this drag reduces the speed of the car at higher speeds. Aerodynamicists try to reduce the drag created by the vortices to use the energy generated by the engine to the maximum.
