Summary:
The mixing performance of complex fluids are compared against those obtained with a standard impeller spindle, to establish which geometry allowed reaching the best level of homogenisation and the more realistic viscosity measurements.
The HRI is calibrated and then used for testing several materials in the field of pavement engineering. The whole experimental programme is simulated by means of CFD analyses.
At last a comparison between CFD particles volume fraction and experimental tests will be carried out to validate CFD simulations and to asses whether CFD modelling could represent a valid support to optimise design and manufacturing efforts of non-standard equipment for rheometry of complex fluids.

Existing and Future Infrastructure
MORPHINE (Re-designing the coast: The Morphodynamics of Large Bodies of Sediment in a Macro-tidal Environment)
Funder: EPSRC
Dates: April 2016-April 2020.
Value: £395,333
Partners: University of Swansea.
Summary:
We are developing a mathematical description of morphodynamics as it pertains to a macro-tidal environment (coastal region with large tidal range, like that in the UK), so as to understand the movement of large deposits of sand on our beaches and shorefaces (shorefaces are, loosely, the regions in between the beach and the continental shelf floor).
This theory will allow us to formulate a new mathematical modelling approach. These models will allow us to develop a new approach to designing sea defences, in which large quantities of sand ("nourishments") are deposited at strategic locations at and / or near to the coastline. These nourishments will provide a source of sediment for beaches that are eroding, but, importantly, they will also alter local wave and current conditions, which will transform previously eroding beaches into more stable configurations, and so form naturalistic coastal defences.
Theory and models, coupled with a new, realistic statistical model of sea conditions, will make it possible for us to predict the behaviour of these nourishments to a reasonable degree of accuracy under different conditions, and with good efficiency. This will support the design sea defences that do not have to rely on invasive, expensive and reactive traditional sea defences.
The work addresses UK conditions in particular, in which a very large tidal range combines with a wide variety of wave conditions to produce a particularly challenging environment. We are therefore proposing to undertake fundamental work on coastal morphodynamics so as to develop tools that will let us re-think our coastal defence strategy.

Splash and Spray Assessment Tool
- Funder: US Federal Highway Administration
- Total value: £300,000
- Start to end date: 2008 – 2012
Summary:
The development of a splash and spray prediction model in this project provides a tool for highway engineers, contributing to decisions concerning the type and priority of maintenance on their network. This could deliver a range of benefits, including increased user satisfaction with the network, reduced accidents and a reduction in the detrimental effects of pollutants being deposited on the verges and street furniture.
