The Influence of Inlet Asymmetry on Steam Turbine Exhaust Hood Flows (2013)
Journal Article
Burton, Z., Hogg, S., & Ingram, G. (2014). The Influence of Inlet Asymmetry on Steam Turbine Exhaust Hood Flows. Journal of Engineering for Gas Turbines and Power, 136(4), Article 042602. https://doi.org/10.1115/1.4026003

It has been widely recognized for some decades that it is essential to accurately represent the strong coupling between the last stage blades (LSB) and the diffuser inlet, in order to correctly capture the flow through the exhaust hoods of steam turb...

Organic Rankine cycles in waste heat recovery: a comparative study (2013)
Journal Article
Auld, A., Berson, A., & Hogg, S. I. (2013). Organic Rankine cycles in waste heat recovery: a comparative study. International Journal of Low-Carbon Technologies, 8(Supplement 1), 9-18. https://doi.org/10.1093/ijlct/ctt033

A theoretical study of organic Rankine cycles (ORCs) powered by three different waste heat sources is presented. The heat sources, all found in industrial processes, span a range of energy scales capable of powering ORCs from ∼10 kW to 10 MW. A novel...

Offshore Wind Farm Asset Management: Past Experiences and Future Challenges. (2013)
Presentation / Conference Contribution
Williams, R., Crabtree, C., & Hogg, S. (2013, June). Offshore Wind Farm Asset Management: Past Experiences and Future Challenges. Presented at ASME Turbo Expo 2013: Turbine Technical Conference and Exposition, San Antonio, USA

This paper considers the asset management of offshore wind farms and, in particular, how this will change as wind farms increase significantly in capacity and move to sites further offshore. Health monitoring, industrial operational structures, infra... Read More about Offshore Wind Farm Asset Management: Past Experiences and Future Challenges..

Reliability Evaluation of New Offshore Wind Farm Electrical Grid Connection Topologies. (2013)
Presentation / Conference Contribution
Kazemtabrizi, B., Crabtree, C., & Hogg, S. (2013, June). Reliability Evaluation of New Offshore Wind Farm Electrical Grid Connection Topologies. Presented at ASME Turbo Expo 2013: Turbine Technical Conference and Exposition, San Antonio, USA

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..

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
