Presentation / Conference Contribution
Messenger, A., Williams, R., Ingram, G., Hogg, S., Tibos, S., & Seaton, J. (2015, June). A Dynamic Clearance Seal for Steam Turbine Application. Presented at ASME Turbo Expo 2015: Turbine Technical Conference and Exposition American Society of Mechanical Engineers, Montreal

Effective sealing in turbomachinery reduces the leakage flow bypassing the turbine blades and also reduces the losses where the leakage flow mixes with the primary flow. In general the clearance should be as small as possible but is limited by therma... Read More about A Dynamic Clearance Seal for Steam Turbine Application..

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.
