THE MOTION DUE TO A CYLINDER ROTATING IN A STRATIFIED FLUID.
Abstract
The steady motions set up by a cylinder rotating in a linearly stratified fluid are investigated both theoretically and experimentally. It is observed that the bulk of the flow is horizontal, characterized by a system of jets located at the level of the cylinder and extending out laterally for large distances. Directly adjacent to either of the cylinder flanks, however, the flow is oriented vertically in a relatively thin boundary layer. Separate visco-diffusive theories for the horizontal 'far-field' flow and the vertical 'near-field' flow are developed. By an integral analysis of the entire flow field it is shown that the far-field flow depends on the details of the near-field flow only through a parametric constant representing the difference between the applied viscous torque and the total buoyancy countertorque which opposes this applied torque.
