A potential novel working fluid for vapour absorption refrigeration utilising very low grade waste heat, is based on acetone and zinc bromide as the salt solution. A Computational Fluid Dynamics (CFD) model is presented of the fluid with zinc oxide n...

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...

Benefits of dry comminution of biomass pellets in a knife mill (2017)
Journal Article
Williams, O., Lester, E., Kingman, S., Giddings, D., Lormor, S., & Eastwick, C. (in press). Benefits of dry comminution of biomass pellets in a knife mill. Biosystems Engineering, 160, https://doi.org/10.1016/j.biosystemseng.2017.05.011

The potential benefits of dry comminution in a knife mill for a diverse range of biomass 6 pellets are explored. The impact of dry comminution on energy consumption, particle size and shape, 7 is examined as well as the link between milling and mecha...

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.
