Abstract

Proceedings of the Institution of Mechanical Engineers, Part G: Journal of Aerospace Engineering, Ahead of Print.
In transonic high-load turbines, interactions between trailing-edge shock waves and suction-side film cooling can severely compromise thermal protection and may even lead to localized cooling failure. To investigate the underlying mechanisms and critical ...
