Film cooling is a commonly used thermal protection technology for turbine airfoils. However,
due to the counter-rotating vortex pair (CVP) generated by the interaction between the …

A novel film-cooling configuration, wherein a groove is integrated into the inlet of a film-
cooling hole, is proposed herein, and its influences are investigated. 3D RANS simulations …

A reconstruction technique of kHz time-resolved two-dimensional (2D) surface temperature
field was achieved with the discrete point measurements and low sampling rate 2D …

Current turbulent heat flux models fail to predict accurate temperature distributions in film
cooling flows. The present paper focuses on a machine learning (ML) approach to this …

Gas turbine film cooling strategies must provide adequate cooling performance under high
levels of mainstream turbulence. Detailed information about the structure, dynamics and …

The design of film cooling systems relies heavily on Reynolds-averaged Navier–Stokes
(RANS) simulations, which solve for mean quantities and model all turbulent scales. Most …
