Experimental Investigation Into Unsteady Effects on Film Cooling

Richard J. Fawcett, Andrew P. S. Wheeler, Li He, Rupert Taylor
Journal: Journal of Turbomachinery
Publisher: ASME
Article Type: Research Papers
J. Turbomach. March 2012, 134(2): 021015.
https://doi.org/10.1115/1.4003053
Published Online: June 28, 2011
...Richard J. Fawcett; Andrew P. S. Wheeler; Li He; Rupert Taylor The benefits of different film cooling geometries are typically assessed in terms of their time-averaged performance. It is known that the mixing between the coolant film and the main turbine passage flow is an unsteady process...

Suction-Side Gill Region Film Cooling: Effects of Hole Shape and Orientation on Adiabatic Effectiveness and Heat Transfer Coefficient

Justin Chappell, Phil Ligrani, Sri Sreekanth, Terry Lucas
Journal: Journal of Turbomachinery
Publisher: ASME
Article Type: Research Papers
J. Turbomach. July 2010, 132(3): 031022.
https://doi.org/10.1115/1.3151600
Published Online: April 7, 2010
...Justin Chappell; Phil Ligrani; Sri Sreekanth; Terry Lucas The performance of suction-side gill region film cooling is investigated using the University of Utah transonic wind tunnel and a simulated turbine vane in a two-dimensional cascade. The effects of film cooling hole orientation, shape...

Large-Scale Testing to Validate the Influence of External Crossflow on the Discharge Coefficients of Film Cooling Holes

D. A. Rowbury, M. L. G. Oldfield, G. D. Lock
Journal: Journal of Turbomachinery
Publisher: ASME
Article Type: Technical Papers
J. Turbomach. July 2001, 123(3): 593–600.
https://doi.org/10.1115/1.1375171
Published Online: February 1, 2000
...D. A. Rowbury; M. L. G. Oldfield; G. D. Lock This paper discusses large-scale, low-speed experiments that explain unexpected flow-interaction phenomena witnessed during annular cascade studies into the influence of external crossflow on film cooling hole discharge coefficients. More specifically...
