A multi-scale analysis of the influence of particle shape on the mechanical response of granular materials |
Dr. Stefanos Papanicolopulos
|
Infrastructure and Environment |
The principal aim is to characterise the flow properties of dense granular systems. In particular, the influence of different particle-shape representation techniques in the Discrete Element Method (DEM) is assessed. Additionally, experiments in a silo centrifuge device to determine the bulk response of granular assemblies under realistic stress states are being carried out. This work is part of T-MAPPP (Training in Multiscale Analysis of multi-Phase Particulate Processes), an FP7 Marie Curie Initial Training Network (https://www.t-mappp.eu).

GECOMPL: Generalised Continuum Models and Plasticity |
Dr Stefanos Papanicolopulos
|
Infrastructure and Environment |
The GECOMPL project aims to enable wider adoption of generalised plasticity models in practical applications. More specifically, the project proposes a detailed study of the formulation of both existing and new elastoplastic constitutive laws in the framework of generalised continua, leading to a better understanding of the different possible constitutive models and providing both the necessary theoretical basis and the appropriate numerical tools needed to use generalised continuum models in describing elastoplastic behaviour.

TROPOS: Modular Multi-use Deep Water Offshore Platform Harnessing and Servicing Mediterranean, Subtropical and Tropical Marine and Maritime Resources |
Professor David Ingram
|
Energy Systems |
TROPOS is a European collaborative project funded by the European Commission under the 7th Framework Programme for Research and Development, more specifically under the "Ocean of Tomorrow" call OCEAN 2011.1 – Multi-use offshore platforms. The TROPOS Project aims at developing a floating modular multi-use platform system for use in deep waters, with an initial geographic focus on the Mediterranean, Tropical and Sub-Tropical regions, but designed to be flexible enough so as to not be limited in geographic scope.

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.

|
Infrastructure and Environment |
Heat transfer in granular materials is a common occurrence in many industrial applications. One such application is the heating of recycled asphalt product (RAP).

The First Open-Source Software for Non-Continuum Flows in Engineering |
Prof Jason Reese
|
Multiscale Thermofluids |
This project is both multi-scale and multi-disciplinary, and spans research areas across physics, mechanical engineering, computer science and chemical engineering. Our aim is to produce, for the first time, a general, robust and efficient open-source code for the simulation of non-continuum flows for engineering applications.

ThermaPower - Thermal Management of High Power Microsystems Using Multiphase Flows |
Professor Khellil Sefiane
|
Multiscale Thermofluids |
Increased functionality and power consumption of microdevices and high power electronics has come at a cost: power dissipation and heating. This heat must be dissipated to ensure reliable operation of such devices in both earthly and reduced gravity environments (eg space industry), without adversely affecting their performance. With a highly competitive world market, worth tens of billions of Euros, it is imperative for EU to gain a competitive position in this field (currently led by USA and China).

TRANSPACC - TRANSient operation of flexible Packings for Carbon Capture |
Dr Prashant Valluri
|
Materials and Processes, Multiscale Thermofluids |
Power plants constitute one of the largest CO2 emitting sectors. With increased emphasis on abatement of emissions to meet the 2030 deadline set by the UK Committee on Climate Change, the power-plant sector is relying on CCS retrofits using post-combustion capture to clean up flue gases. However, despite the highly transient nature of power plant operation characterised by frequent shut-downs and start-ups (up to twice a day), the retrofits are currently designed for a constant base-load operation and hence cannot maintain even liquid distribution during unsteady loading.
