Summary on Grant Application Form
The proposal seeks support for a Visiting Fellow to enable a joint investigation to be carried out into (i) the response of a contained, rotating, stratified fluid to boundary forcing and (ii) the mixing produced within the fluid as a result of the boundary forcing. The project is complementary to a current EPSRC grant on driven cavity flow and is an extension of a previous joint investigation with the Visiting Fellow on layer formation in a shear-driven, non- rotating, stratified fluid. The primary application is to the environmental fluid mechanics of large reservoirs or lakes subjected to surface wind stress. series of laboratory model experiments will investigate the flow generated by the rotation of a roughened baseplate in a rotating stratified fluid. Emph will be placed on the role of background rotation and boundary turbulence in generating (i) a mixed layer adjacent to the rotating disk and (ii) internal mixed layers in the fluid interior. The detailed structure of the mixed layer velocity and density fields will be measured and the growth with time of the layers will be parameterised in terms of the magnitudes of the initial stratification, surface forcing and background rotation rate. The occurrence of secondary circulations within the fluid will be investigated and the role of these circulations in influencing and controlling the formation of internal mixe layers will be determined. Comparisons will be made between the experimental data and the predictions of an existing scaling analysis developed t the proposer and Visiting Fellow and the application of the results to the environmental and industrial counterpart flows will be made.
