Flow Measurements in a First Stage Nozzle Cascade Having Endwall Contouring, Leakage, and Assembly Features

J. D. Piggush, T. W. Simon
Journal: Journal of Turbomachinery
Publisher: ASME
Article Type: Research-Article
J. Turbomach. January 2013, 135(1): 011002.
Paper No: TURBO-07-1131

Comparison of Steady and Unsteady RANS Heat Transfer Simulations of Hub and Endwall of a Turbine Blade Passage

Lamyaa A. El-Gabry, Ali A. Ameri
Journal: Journal of Turbomachinery
Publisher: ASME
Article Type: Research Papers
J. Turbomach. July 2011, 133(3): 031010.
https://doi.org/10.1115/1.4002412
Published Online: November 15, 2010
...Lamyaa A. El-Gabry; Ali A. Ameri The necessity of performing an unsteady simulation for the purpose of predicting the heat transfer on the endwall surfaces of a turbine passage is addressed. This is measured by the difference between the two solutions obtained from a steady simulation and the time...
