Numerical study of wetting transitions on biomimetic surfaces using a lattice Boltzmann approach with large density ratio (2017)
Journal Article

The hydrophobicity of natural surfaces have drawn much attention of scientific communities in recent years. By mimicking natural surfaces, the manufactured biomimetic hydrophobic surfaces have been widely applied to green technologies such as self-cl...

Immiscible thermo-viscous fingering in Hele-Shaw cells (2017)
Journal Article

We investigate immiscible radial displacement in a Hele-Shaw cell with a temperature dependent viscosity using two coupled high resolution numerical methods. Thermal gradients created in the domain through the injection of a low viscosity fluid at a... Read More about Immiscible thermo-viscous fingering in Hele-Shaw cells.

The stability of immiscible viscous fingering in Hele-Shaw cells with spatially varying permeability (2017)
Journal Article

In this paper, we investigate the stability of immiscible viscous fingering in Hele-Shaw cells with spatially varying permeability, across a range of capillary numbers. We utilise a coupled boundary element - radial basis function (BE –RBF) numerical...

Overcoming the caking phenomenon in olive mill wastes (2017)
Journal Article

The use of olive mill wastes (orujillo) within coal fired power stations in the UK has led to unexpected difficulties with material caking within the fuel handling plant. This study replicated orujillo caking on a laboratory scale using a planetary b... Read More about Overcoming the caking phenomenon in olive mill wastes.

Influence of mill type on densified biomass comminution (2016)
Journal Article

The impact of different mill fracture mechanisms were examined for a wide range of densified biomass pellets to provide a comprehensive analysis of biomass milling behaviour for pulverised fuel combustion. The milling behaviour of 7 woody, herbaceous... Read More about Influence of mill type on densified biomass comminution.

An adaptive RBF finite collocation approach to track transport processes across moving fronts (2015)
Journal Article

© 2015 Elsevier Ltd. We develop a radial basis function finite collocation method (RBF-FC) that utilises an adaptive quadtree dataset to cluster nodes around critical features in the domain, for the solution of transport processes occurring in moving...

Impact of mill type on biomass mill behavior (2015)
Conference Proceeding

With increasing use of biomass in pulverized fuel coal fired power stations, the impact of mill type on biomass size and shape is fundamental in optimizing mill and burner performance. The impact of mill type on the energy consumption, particle size... Read More about Impact of mill type on biomass mill behavior.

Investigation into the applicability of Bond Work Index (BWI) and Hardgrove Grindability Index (HGI) tests for several biomasses compared to Colombian La Loma coal (2015)
Journal Article

With increasing quantities of biomass being combusted in coal fired power stations, there is an urgent need to be able to predict the grindability of biomass in existing coal mills, but currently no standard biomass grindability test exists. In this... Read More about Investigation into the applicability of Bond Work Index (BWI) and Hardgrove Grindability Index (HGI) tests for several biomasses compared to Colombian La Loma coal.

The impact of moisture on the milling behavior of different biomasses (2014)
Conference Proceeding

The aim of this study was to examine the impact of moisture content on the milling behaviour of four different biomasses commonly used in the power sector and characterise their milling behaviour in a laboratory scale planetary ball mill. As received... Read More about The impact of moisture on the milling behavior of different biomasses.

Numerical analysis of particle flows within a double expansion (2014)
Journal Article

The effect of solid particles within flows having zones of recirculation is of interest in pulverised fuel distribution and combustion at burners. Previous modelling of a 1/4 scale test rig was performed by Giddings et al. (2004), and an instability... Read More about Numerical analysis of particle flows within a double expansion.

Optimisation of biomass milling for conveyance and combustion (2013)
Conference Proceeding

Agricultural wastes are increasingly being used as biomass materials for co-firing in coal fired power stations. However issues in milling and conveyance of agricultural residues are limiting the use of these resources and a greater understanding of...
