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.

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.

FireComp: Modelling the thermo-mechanical behaviour of high pressure vessel in composite materials when exposed to fire conditions |
Dr Stephen Welch
|
Infrastructure and Environment |
Hydrogen is expected to be highly valuable energy carrier for the 21st century as it should participate in answering main societal and economical concerns. To exploit its benefits at large scale, further research and technological developments are required. In particular, the storage of hydrogen must be secured. Even if burst in service of pressure vessels in composite material is very unlikely, when exposed to a fire, they present safety challenges imposing to correctly size their means of protection.

Fire Safety of Modern Timber Infrastructure |
Dr Rory Hadden
|
Infrastructure and Environment |
Exposed structural timber elements within a compartment creates an additional fuel load which must be considered in design. This research focuses on quantifying this additional fuel load, and understanding conditions where after burnout of the compartment contents, the additional exposed timber may stop burning (auto-extinguish).

Finite element implementation and detailed comparison of generalised plasticity models |
Dr. Stefanos Papanicolopulos
|
Infrastructure and Environment |
The lack of an internal length scale parameter in classical continua leads to unrealistic numerical modelling of some phenomena related to the microstructure of the material such as size effect and strain localisation.

Feasibility of a wetting layer absorption carbon capture process based on chemical solvents |
Professor Stefano Brandani
|
Materials and Processes |
New ideas for carbon capture are urgently needed to combat climate change. Retro-fitting post-combustion carbon capture to existing power plants has the greatest potential to reduce CO2 emissions considering these sources make the largest contribution to CO2 emissions in the UK. Unfortunately, carbon capture methods based on existing industrial process technology for separation of CO2 from natural gas streams (i.e. amine scrubbing) would be extremely expensive if applied on the scale envisaged, as exemplified by the recent collapse of the Government's CCS project at Longannet power station. Moreover, many of the chemical absorbents used, typically amines, are corrosive and toxic and their use could generate significant amounts of hazardous waste. So, more efficient and 'greener' post-combustion CCS technologies are urgently needed if CCS is to be adopted on a global scale.

FLOWBEC - FLOW and Benthic Ecology 4D |
Dr Angus Creech
|
Energy Systems |
The FLOWBEC project aims to improve the understanding of how the physical behaviour of the water such as currents, waves and turbulence at tide and wave energy sites influences the behaviour of marine wildlife, and how tide and wave energy devices might alter the behaviour of such wildlife.

Enhanced oil/gas recovery and CO2 storage |
Dr Xianfeng Fan
|
Materials and Processes |
Enhanced oil/gas recovery and CO2 storage are a displacement process at pore scale, in which oil and gas are displaced by water or CO2 in reservoir at pore scale, or water is displaced by CO2 in aquifers at pore scale. This displacement is controlled by pore structure, pore wettability, pore surface chemistry, fluid viscosity and interfacial interaction between pore fluids and pore surfaces. The displacement controls the pore connectivity, therefore oil/gas recovery and CO2 storage capacity. We investigate the displacement and the effect of various factors on the displacement at pore scale and core scale.
