Numerical Investigation of Three Dimensional Laminar Flows in a Channel with a Built-in Circular Cylinder and Wing-Type Vortex Generators
Laminar flows around a circular cylinder in a rectangular channel with a pair of built-in vortex generators in form of delta winglets on the bottom plate of the channel have been investigated by solving the complete Navler Stokes equations with a Marker-and-cell technique. Results show that longitudinal vortices from the vortex generators placed in the wake of the cylinder not only control the spread of the wake of the cylinder but also completely damp the periodic vortex street.
