Unsteadiness in the Secondary Flows of a High-Speed Low-Pressure Turbine Cascade With Unsteady Wakes and Purge Flow

Gustavo Lopes, Sergio Lavagnoli
Journal: Journal of Turbomachinery
Publisher: ASME
Article Type: Research Papers
J. Turbomach. September 2025, 147(9): 091017.
Paper No: TURBO-24-1152
https://doi.org/10.1115/1.4067674
Published Online: February 17, 2025
...Gustavo Lopes; Sergio Lavagnoli This work investigates the unsteady interactions between incoming wakes and purge flow in a high-speed low-pressure turbine cascade tested under engine-representative conditions. Experiments were conducted in a linear cascade at outlet Mach and Reynolds numbers...
