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.
Low intensity prescribed fires are often employed in forests and wildland in order to manage hazardous fuels, restore ecological function and historic fire regimes, and encourage the recovery of threatened and endangered species. Current predictive models used to simulate fire behavior during low-intensity prescribed fires (and wildfires) are empirically-based, simplistic, and fail to adequately predict fire outcomes because they do not account for variability in fuel characteristics and interactions with important meteorological variables. Experiments are being carried out at scales ranging from the fuel particle, to fuel bed, to field plot and stand scales, with an aim of better understanding how fuel consumption is related to the processes driving heat transfer, ignition and flame spread, and thermal degradation through flaming and smouldering combustion, at the scale of individual fuel particles and fuel layers. Focus is placed on how these processes, and thus fuel consumption, are affected by spatial variability in fuel particle type, fuel moisture status, bulk density, and horizontal and vertical arrangement of fuel components, as well as multi-scale atmospheric dynamics.
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).
As part of a DETR funded PiT (Partners in Technology) project the BRE Centre for Fire Safety Engineering (previously the Structures in Fire Group) conducted extensive computational and analytical studies of the behaviour of steel-framed composite structures in fire conditions. This work was undertaken in collaboration with Corus PLC and Imperial College London. The results were presented in the form of a main report, which identified the main findings, together with numerous supplementary reports which explored various phenomena in detail. The reports produced at Edinburgh are available for download as indicated below.
My research focuses on the removal of selected micro contaminants and potential Endocrine Disrupting Compounds (EDCs) from water and wastewater by means of the photocatalytic process as well as on the investigation of method’s sustainability.
This project aims at identifying the mechanisms involved during the removal of different types of chlorophenols using several biochars during water treatment. Chlorophenols and biochars with different physico-chemical properties will be tested as well as different environmental characteristics.
A project, funded by PhD scholarships from the Islamic Development Bank and EPSRC (via the Doctoral Training Grants) is underway looking at the efficiency of meso-scale waste stabilization ponds to treat municipal waste water, with resource recovery from fish farming and selling sludge for fertilizer. The ultimate aim is to demonstrate systems that can be adpoted and run by communities, particularly in urban West Africa. The pilot project is based in Cotonou, Benin.
