Görtler vortices

Görtler vortices are a phenomenon that occurs in boundary layer flow, particularly in the context of fluid dynamics. They are a type of flow instability that develops in the presence of curved surfaces, such as in the flow over a flat plate with a concave shape or in the vicinity of a wing's leading edge. These vortices form due to the interaction between the curvature of the surface and the boundary layer of fluid that adheres to it.
