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. WebVortex generators are typically used in the following applications: Swept wings at transonic speed: Many early swept wings were found to suffer from separation at transonic speeds …
