Abstract:

The autorotation of plates normal to a uniform parallel flow is explained in detail for low Reynolds numbers by means of numerical solutions of the Navier-Stokes equations. The incompressible fluid flow is assumed to be laminar and two-dimensional. Comparisons are made with high Reynolds number and three-dimensional flows. The article defines autorotation, gives an historical account of investigations into autorotation, and shows that autorotation is caused by a complicated interplay of vortex shedding, boundary-layer hysteresis, and vorticity generation around the edges of the plate.
