Abstract
- •Film cooling of C3X vane with serrate-type trenched holes using mist/air mixture under practical conditions is evaluated.•Both serrated transverse trench structure and addition of mist to air can significantly improve film cooling performance.•Replacing the trench edge by a double-curvature lip structure can further improve the film cooling effectiveness.•Film cooling effectiveness of the vane is reduced when the angle of the serrated trench is too large.•Vortex for the six trenched holes intensifies with the increase in the mass flow rate.
