Development and use of an advanced ZVI nanomaterial for water treatment applications |
Dr Andrea Joana Correia Semiao, Dr Blanca Antizar-Ladislao
|
Infrastructure and Environment |
Miss Underwood's doctoral research seeks to develop and test new nano-composite materials for the use in water treatment. She wishes to improve upon the existing nano zero-valent iron technologies as well as to explore how specific nanotechnologies can be applied in an economic and incentivized fashion for successful technological adoption.

Signal Processing in the Information Age |
Prof Michael E Davies
|
Imaging, Data and Communications |
The aim of the UDRC is to develop unprecedented research in signal processing with application to the defence industry and share knowledge, promote communications, guidance and training. The formation of consortia will bring together researchers from across the different aspects of signal processing to address the research challenges of operating in a networked battlespace. This will form part of a wider collaborative centre of excellence for signal processing that embraces academia, Research and Technology Organisations, defence manufacturing industries and the Defence Technology Centres. This collaboration will support a cutting edge signal and data processing capability in the UK, and lead to potentially greater research impact.

Simulation of dense suspensions with discrete element method and a coupled lattice Boltzmann method |
Dr. Jin Sun
|
Infrastructure and Environment |
Suspensions, mixtures of a fluid and particles, are widespread in nature and industry. However, many open questions, such as the particle interactions in dense suspensions, have not been answered [1].

Dr Kevin Hanley
|
Infrastructure and Environment |
The objective of this research is to investigate the behavior of Dunkerque sand under undrained triaxial cyclic loading using the discrete element method (DEM).

Simulation of Irregular, Abradable Particles in DEM |
Dr Kevin Hanley
|
Infrastructure and Environment |
Particle shape has important effects on bulk materials as sandpiles and mixtures; temporal changes of the shape (e.g. due to surface abrasion) also have severe consequences in many industrial sectors. To represent irregular particles, a compact “irregularity function” can be stored for each particle which describes how the shape deviates from a bounding sphere. Abrasion can be studied by adopting irregularity functions which can change with time depending on contact force.

Rheology of Dense Suspension System containing Frictional and Frictionless Particles |
Dr. Jin Sun
|
Infrastructure and Environment |
From cement and ceramic pastes to paints and drilling fluids, dense suspensions of solid particles immersed in a liquid are ubiquitous in industries. Understanding the rheology of dense suspensions is important for explaining and predicting the multiphase flow behavior in traditional and innovative industrial processes. In this project, DEM simulations are employed to understand the rheology of suspensions containing different particles with different surface properties.

Measurement and modelling of powder flow in flexible containers |
Prof. Jin Ooi
|
Infrastructure and Environment |
The research focuses on understanding cohesive powder flow in flexible bulk solid containers (buggies and bulk bags) with a view to develop a design methodology for ensuring reliable discharge from these containers. The project involves experimental powder flowability characterisation, finite element analysis of the stresses in flexible containers and pilot scale experiments to study the powder flow field and validate the new design methodology for reliable discharge.

Models for manufacturing of particulate products |
Professor Jin Ooi
|
Infrastructure and Environment |
This project aims to create a generally applicable framework for transferring academic innovations in the modelling of particulate materials into industrial practice in the UK. The process of twin-screw granulation has been selected as an exemplar industrial process which is simulated across multiple scales using the coupled methods of population balance modelling and the discrete element method.
