Three dimensional vortex dynamics near a wall
Abstract
The three-dimensional deformation of an artificially generated line vortex near a flat wall is examined by means of flow visualization and quantitative conditioned sampling of a hot wire anemometer. The vortex is observed to undergo a very rapid deformation from the rectilinear form to a hairpinlike shape. Similar shapes have been observed in the case of driven flows in laminar boundary layers. In the present case the vortices are driven by a rotor configuration of larger scale than the boundary layer thickness.
