Within the Fluid Mechanics research sub-group (Prof Peter Davies FRSE, Prof Ping Dong, Prof Dong-Sheng Jeng, Dr Jonathan Kobine, Dr Ian Mackie, Dr Yong Sung Park, Prof Alan Vardy FREng FRSE) modelling and field studies are being used to investigate a wide range of problems in environmental, industrial, medical and physical fluid mechanics. Most of these studies are concerned with flows having direct engineering relevance, though other more fundamental investigations are undertaken of other fluid dynamical phenomena that have no direct technological applications.
The group has developed a particular strength in environmental fluid mechanics with broad interests in coastal, offshore and estuarine flows, wave-sediment processes, ocean wave modelling, aquifer flows, air flows in rail and road tunnels, and low Reynolds number flows in water filtration systems. The wide range of research activities of the group also includes fundamental investigations of non-linear processes in fluid systems, fluid-solid interactions, medical fluid dynamics and flow-control devices. The group has invested in computer-based flow data acquisition and analysis systems, together with advanced micro-conductivity probes for measurements of turbulent density fields in stratified flows. Its laboratories are equipped with a large stratified flow channel, a tidal flow facility, an internal wave tank, several rotating tables and computer-controlled platforms for investigating oscillating fluid systems.
Environmental topics presently under investigation include buoyancy-driven exchange flows over estuarine barriers, dispersal of particulates from wastewater discharges, flow-topography interactions, gravity currents, oceanic outflows, waves and turbulence and mixing in rotating stratified fluids, safety and ventilation in road and rail tunnels, pressure transients in high speed tunnels, unsteady friction in pipe flows, coastal morphodynamics, wave-soil-structure interactions, cliff erosion, probabilistic modelling of evolutions of mixed beaches, stability and breaking of internal solitary waves, and turbulent buoyant jets. Many of the above studies are being carried out in collaboration with groups in other institutions and other disciplines. Strong collaborative research links exist with colleagues at Aberdeen, St Andrews, Edinburgh, Manchester, Cambridge, Plymouth, Oslo, Gothenburg, Bergen, Arizona State and Ohio State Universities and the Scottish Association of Marine Sciences (SAMS).
