Abstract: An experimental investigation has been performed to study the film-cooling performance of the cylindrical holes embedded in the sine-wave-shaped-trench. The sine-wave-shaped-trench is obtained by changing the trailing edge ...

Abstract: The film cooling characteristics of the transverse trench (TT) and the double-wave trench (DWT) were numerically studied by using Reynolds-averaged Navier–Stokes simulations with realizable k–ɛ turbulence model and enhanced ...
