The successful demonstration of the “Aerostatic Seal” in a half scale rotating facility is described in this paper. The Aerostatic seal is a novel dynamic clearance seal specifically designed for steam turbine secondary gas path applications. The sea...

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). Application of an Air-Curtain Fluidic Jet Type Seal to Reduce Turbine Shroud Leakage. In Proceedings of the ASME turbo expo - Turbine technical conference and exposition 2013 : presented at the ASME 2013 turbo expo - Turbine technical conference and exposition, June 3-7, 2013, San Antonio, Texas, USA. https://doi.org/10.1115/gt2013-94198

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.
