3 Re = 2ur (1) In Equation 1, Re is the Reynolds number of the shape, uis the wind velocity in unobstructed flow, r is the radius of the curvature and is the kinematic viscosity of air. Sub-critical flow over a smooth cylinder generally occurs at Re less than 2x10 5.Sub-critical flows are characterized by laminar flow over the windward surface of the cylinder with the flow

by Stokes to mean that there was no stable flow pattern for the cylinder; experiments, however, showed this conclusion to be incorrect. The non-existence of a solution to the Stokes equations for the steady motion of fluid past a 2 circular cylinder has become known as the Stokes paradox. The Stokes paradox remained unresolved for many years
