Multiscale characterisation of randomly oriented board strand composites from re-used prepreg scrap |
Francisca Martinez Hergueta
|
The aim of this project is to develop manufacturing upcycling technologies to re-use prepreg scrap and determine the resultant mechanical properties. This project mitigates the environmental impact of conventional composite manufacturing processes reducing air emissions and energy consumption. It also contributes towards a sustainable economy reducing the waste disposal fees paid by commercial companies and recovering commercial value from the composite scrap.

Models for manufacturing of particulate products |
Professor Jin Ooi
|
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.

Measurement and modelling of powder flow in flexible containers |
Prof. Jin Ooi
|
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.

Rheology of Dense Suspension System containing Frictional and Frictionless Particles |
Dr. Jin Sun
|
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.

Simulation of Irregular, Abradable Particles in DEM |
Dr Kevin Hanley
|
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.

Simulation of dense suspensions with discrete element method and a coupled lattice Boltzmann method |
Dr. Jin Sun
|
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].

Development and use of an advanced ZVI nanomaterial for water treatment applications |
Dr Andrea Joana Correia Semiao, Dr Blanca Antizar-Ladislao
|
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.

Effect of particle shape, size and particle friction in granular solid flow in railway ballast |
Prof. Xuecheng Bian
|
In the Chinese southeast coastal areas, most of the rail transit infrastructures are built on the soft soil. Infrastructures construction and operation including high speed railway or urban railway system require a good understanding of the behavior of the soft soil subject to the static and dynamic loading induced by the infrastructure.
