Understanding the environmental impacts of wastewater discharges into oceans, dredged material disposal in coastal marine waters and atmospheric emissions from industrial stacks and volcanoes, requires detailed knowledge of how the multiphase (fluid + particulate) behaviour of buoyant jets and plumes is affected by the source conditions (e.g. momentum and buoyancy fluxes, plume geometry, etc.). Obtaining reliable measurements at source can, however, prove difficult due to their inaccessibility (e.g. discharges from deep ocean outfalls, oil spills from seabed pipeline fractures or eruptions from volcanic vents). As such, well-established theories for buoyant jet and plume behaviour typically assume time-averaged source conditions, thus disconnecting any inherent source irregularities (unsteadiness, or variability?) from the more accessible measurements of downstream plume behaviour, such as entrainment characteristics, rise and spreading heights, umbrella cloud formation and collapse mechanisms, and particulate fallout and deposition patterns.

Course programme
Over the past 16 years, Civil Engineering research at Dundee has maintained its ranking as 1st in Scotland and in the top 10 in the UK. A major contributor to this success has been the internationally-recognised research in Environmental Fluid Mechanics with applications in ocean, coastal, offshore and estuarine flows, fluid-structure interactions, sediment transport processes, marine renewable energy, and computational fluid dynamics combining big data and machine learning. The Fluid Mechanics group has a highly successful track record in winning external research grants from national and international funding agencies and industry. It has excellent research and testing facilities, including wave flumes and recirculating flow tanks, as well as the £2M Scottish Marine and Renewables Testing (SMART) Centre, for research at the fluid-structure or fluid-soil interfaces.
