In this paper, a composite generation transmission approach has been chosen for adequacy evaluation of wind farms integrated with conventional generating units. It has been assumed that the failure characteristics of a turbine’s underlying subassembl... Read More about Reliability Evaluation of New Offshore Wind Farm Electrical Grid Connection Topologies..

Plasmon-loss imaging of polymer-methanofullerene bulk heterojunction solar cells (2013)
Journal Article
Mendis, B. G., Bishop, S. J., Groves, C., Szablewski, M., Berlie, A., & Halliday, D. P. (2013). Plasmon-loss imaging of polymer-methanofullerene bulk heterojunction solar cells. Applied Physics Letters, 102(25), Article 253301. https://doi.org/10.1063/1.4812485

The plasmon feature in an electron energy loss spectrum provides unique insight into poly(3-hexylthiophene) (P3HT)-phenyl-C61-butyric acid methyl ester (PCBM) solar cells. Analysis of the intensity, shape, and energy of the plasmon reveals informatio... Read More about Plasmon-loss imaging of polymer-methanofullerene bulk heterojunction solar cells.

Network planning case study utilising real-time thermal ratings and computational fluid dynamics (2013)
Presentation / Conference Contribution
Greenwood, D., Ingram, G., Taylor, P., Collinson, A., & Brown, S. (2013, June). Network planning case study utilising real-time thermal ratings and computational fluid dynamics. Presented at Electricity Distribution (CIRED 2013), 22nd International Conference and Exhibition on Electricity Distribution., Stockholm, Sweden

Real-Time Thermal Ratings (RTTR) has a natural synergy with wind generation, since during periods of high local wind speed increased wind farm output coincides with uplifted line ratings. This paper describes a network planning study on a real sectio... Read More about Network planning case study utilising real-time thermal ratings and computational fluid dynamics.

Application of an Air-Curtain Fluidic Jet Type Seal to Reduce Turbine Shroud Leakage (2013)
Presentation / Conference Contribution
Auld, A., Hilfer, M., Hogg, S., Ingram, G., & Messenger, A. (2013, June). Application of an Air-Curtain Fluidic Jet Type Seal to Reduce Turbine Shroud Leakage. Presented at ASME Turbo Expo 2013., San Antonio, USA

This paper describes the design and optimization of an ‘air-curtain’ type seal using a fluidic jet to reduce tip leakage losses on a small high-speed single stage axial turbine device. The application will essentially demonstrate proof of concept for... Read More about Application of an Air-Curtain Fluidic Jet Type Seal to Reduce Turbine Shroud Leakage.

A Novel Method of Coupling the Steam Turbine Exhaust Hood and the Last Stage Blades Using the Non-Linear Harmonic Method (2013)
Presentation / Conference Contribution

Waste biomass from production process co-firing with coal in a steam boiler to reduce fossil fuel consumption: A case study (2013)
Journal Article
Gu, H., Zhang, K., Wang, Y., Huang, Y., Hewitt, N., & Roskilly, A. P. (2013). Waste biomass from production process co-firing with coal in a steam boiler to reduce fossil fuel consumption: A case study. Journal of Energy Chemistry, 22(3), 413-419. https://doi.org/10.1016/s2095-4956%2813%2960054-6

Waste biomass is always generated during the production process in industries. The ordinary way to get rid of the waste biomass is to send them to landfill or burn it in the open field. The waste may potentially be used for co-firing with coal to sav...
