Analysis of low speed unsteady airfoil
Furthermore, certain “steady” flows are inherently unsteady in the presence of flow separation, as for example the unsteady flow caused by the karman vortex shedding downstream of a cylinder and “static” airfoil stall which is an inherently unsteady flow phenomenon.
