The trailing edge of gas turbine blades encounters concentrated heat loads, necessitating cooling techniques distinct from those used in mid-chord regions. Narrow channels these areas typically incorporate pin fins or dimples for internal cooling. In contrast, external relies on cutback film configurations, which differ significantly designs. Large eddy simulation (LES) has emerged as a powerful tool investigating transfer challenging environments, capturing intricate flow phenomena and turbulence effects that Reynolds-Averaged Navier–Stokes (RANS) simulations often cannot resolve. This review synthesizes findings 54 LES-based studies cooling, focusing three key configurations: fin arrays, dimpled surfaces, LES consistently demonstrated higher accuracy predicting effectiveness, outperforming RANS by resolving complex structures such horseshoe vortices, shear layer unique interactions inherent to geometries. Furthermore, provided detailed statistics local distributions, offering critical insights optimizing improving predictive models. Beyond its capabilities, this underscores the future potential advancing shape optimization, transient analysis, multi-physics simulations, including conjugate flow-structure interactions.
