Flow within a large-aspect-ratio cylindrical vortex cell has been explored experimentally. The flow was driven by a shear layer above an opening in the cylinder circumference. Reynolds numbers, based on the length of the opening and the velocity just outside it, exceed 50,000. It is shown that the expected solid body rotation within the cell, with a constant velocity gradient across most of the core, is qualitatively present, but is significantly distorted by three-dimensional effects… CONTINUE READING
