Nano-particle deposition in the presence of electric field (2018)
Journal Article
Talebizadeh Sardari, P., Rahimzadeh, H., Ahmadi, G., & Giddings, D. (2018). Nano-particle deposition in the presence of electric field. Journal of Aerosol Science, 126, 169-179. https://doi.org/10.1016/j.jaerosci.2018.09.012

The dispersion and deposition of nano-particles in laminar flows in the presence of an electric field were studied. The Eulerian-Lagrangian particle tracking method was used to simulate nano-particle motions under the one-way coupling assumption. For...

Applicability of mechanical tests for biomass pellet characterisation for bioenergy applications (2018)
Journal Article
Williams, O., Taylor, S., Lester, E., Kingman, S., Giddings, D., & Eastwick, C. (2018). Applicability of mechanical tests for biomass pellet characterisation for bioenergy applications. Materials, 11(8), Article 1329. https://doi.org/10.3390/ma11081329

In this paper, the applicability of mechanical tests for biomass pellet characterisation was investigated. Pellet durability, quasi-static (low strain rate), and dynamic (high strain rate) mechanical tests were applied to mixed wood, eucalyptus, sunf...

Wet steam measurement techniques (2018)
Journal Article
Walker, D., Barham, S., Giddings, D., & Dimitrakis, G. (2019). Wet steam measurement techniques. Reviews in Chemical Engineering, 35(5), 627-648. https://doi.org/10.1515/revce-2017-0078

In recent years a greater need for power station efficiency has become evident; improving turbine blade efficiency is one of the methods proposed. This efficiency relies upon the wetness of the steam that comes into contact with the blades of the low... Read More about Wet steam measurement techniques.

CFD simulation of a concentrated salt nanofluid flow boiling in a rectangular tube (2018)
Journal Article
Mohammed, H. I., Giddings, D., & Walker, G. S. (2018). CFD simulation of a concentrated salt nanofluid flow boiling in a rectangular tube. International Journal of Heat and Mass Transfer, 125, 218-228. https://doi.org/10.1016/j.ijheatmasstransfer.2018.04.069

© 2018 Elsevier Ltd Improvement of heat transfer and critical heat flux (CHF) via nanofluid in pool boiling is well known. Flow boiling is usually represented by heat transfer correlations. But in the case of a concentrated salt solution nanofluid, t... Read More about CFD simulation of a concentrated salt nanofluid flow boiling in a rectangular tube.
