A Dynamic Clearance Seal for Steam Turbine Application. (2015)
Conference Proceeding
Messenger, A., Williams, R., Ingram, G., Hogg, S., Tibos, S., & Seaton, J. (2015). A Dynamic Clearance Seal for Steam Turbine Application. In Proceedings of the ASME Turbo Expo 2015: Turbine Technical Conference and Exposition, June 15-19, 2015, Montreal, Quebec, Canada. Volume 8: Microturbines, Turbochargers and Small Turbomachines; Steam Turbines. https://doi.org/10.1115/gt2015-43471

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..

Experimental Validation of a Curtain Type Fluidic Jet Seal on a Turbine Rotor Shroud (2015)
Conference Proceeding
Montreal, Quebec, Canada, June 15–19, 2015. https://doi.org/10.1115/gt2015-42624

This paper describes the design and testing of a fluidic “air-curtain” type seal application to reduce tip leakages on a small high-speed single stage axial turbine. The initial experimental investigations were carried out to demonstrate the applicat... Read More about Experimental Validation of a Curtain Type Fluidic Jet Seal on a Turbine Rotor Shroud.

Efficient Methods for Predicting Low Pressure Steam Turbine Exhaust Hood and Diffuser Flows at Design and Off-Design Conditions (2015)
Journal Article
Burton, Z., Ingram, G., & Hogg, S. (2015). Efficient Methods for Predicting Low Pressure Steam Turbine Exhaust Hood and Diffuser Flows at Design and Off-Design Conditions. Journal of Engineering for Gas Turbines and Power, 137(8), https://doi.org/10.1115/1.4029599

The exhaust hood of a steam turbine is an important area of turbomachinery research as its performance strongly influences the power output of the last stage blades (LSB). This paper compares results from 3D simulations using a novel application of t...
