Summary on Grant Application Form
This study comprises an inter-disciplinary investigation (via an interactive sequence of theoretical/numerical and laboratory studies) of the dynamics of a range of classes of contained, rotating stratified flows. A density-stratified fluid contained in an axisymmetric cavity (which may itself be rotating) is to be driven by the combined action of a rotating horizontal lid and/or an inner, axially-aligned, spindle. The inner spindle is allowed to vary in diameter in order to assess the influence upon the flow of a changing cavity cross-section and its interaction with buoyancy forces due to the internal (initially stable) density stratification. The presence of 'sloping' boundaries introduces important new physical processes that not only couple buoyancy forces into the nonlinear driving mechanisms of the flow, but also greatly complicate the propagation of inertial-gravity waves and any consequent internal mixing of the fluid. The nonlinear interaction of buoyancy forces and the complex flow/wave mechanisms present in rotating fluids play a dominant role in many applications ranging from water quality aspects of circulations in large reservoirs and lakes to performance characteristics of magnetic data storage devices and crystal growth technologies. Close collaboration with a leading industrial company (AEA) will enhance the numerical investigations and facilitate comparisons between theoretical and laboratory model data. The principal outcome of this work will be a detailed quantitative classification of the flow for a range of forcing and geometrical conditions and a delineation of the processes affecting such flow behaviour
