Influence of snow structure and properties on the grip of winter tyres |
Dr Jane Blackford
|
Materials and Processes |
The aim of this project is to investigate the friction of rubber and tyre treads on snow. It is a collaborative project with Michelin. We use tribological testing and materials characterisation techniques in a specially designed cold room facility to do this. Ultimately this knowledge will be used to improve tyre traction on snow.

|
Infrastructure and Environment |
We examine the rheology of granular dense suspensions using computer simulations with discreste particles and develop constitutive models for flow of such suspensions.

Dense suspension rheology through DEM simulations |
Dr. Jin Sun
|
Infrastructure and Environment |
Mud, slurry, coffee, paints, cements, batteries and many other everyday materials have particles suspended in a liquid. We need to understand the flow behaviour to handle, and process such materials for traditional and innovative applications. Our research seeks to understand the common features of the flow behaviour of different materials using simple particle based simulations. In particular, we focus on dense suspensions where the particles occupy more than 50 % by volume of the solution.

Flow and sintering of non-spherical particles in additive manufacturing |
Dr. Jin Sun
|
Infrastructure and Environment |
The Edinburgh part of the project focues on the multi-physics modelling of particle dynamics and sintering behaviour in selective laser sintering processes. This work is an integrated part of an EPSRC funded project to develop fundamental understanding of particle behavour in additive manufacturing, collaborating with the University of Exeter. This project proposes to investigate the way polymeric powders of different shapes and sizes flow, interact and sinter in the laser sintering process, through modelling and experimental validation. Laser sintering is part of the additive manufacturing technology, known for its benefits in industries where custom made products, lightweight and complex designs are required.

Particle Dynamics and suspension rheology in electrical discharge |
Dr. Jin Sun
|
Infrastructure and Environment |
The Edinburgh part of the project focuses on multi-physics modelling of particle dynamics and suspension rheology in electrical discharge processes. This work is an integrated part of an EPSRC funded project to develop novel electrical discharge methods (EDM) for functional surface coating, collaborating with The University of Nottingham. This project aims to revolutionise the way industrial electrical discharge machining processes can be used. It will transform the process from a machining only technique to a method that is also capable of novel surface treatments at the same time.

TorqTidal: Mitigating Torque Pulsations in Tidal Current Turbines |
Dr Jonathan Shek
|
Energy Systems |
TorqTidal seeks to provide control strategies for tidal current turbines that will reduce the risk of failure and increase the lifetime of device components without increasing capital costs. This will act to increase investor confidence and drive down the LCOE, which is a key step in helping the UK to exploit its significant tidal energy resource.

Electro-Mechanical Modelling of Tidal Turbines |
Dr Jonathan Shek
|
Energy Systems |
The research in this project will focus on modelling full resource-to-wire dynamic models of tidal arrays in order to investigate and optimise their operation. The expected impact of this study is providing industry with an understanding and guidelines of the applicability of the different electrical layouts to specific locations and size of the arrays.
