METHOD AND STRUCTURE FOR COOLING AIRFOIL SURFACES USING ASYMMETRIC CHEVRON FILM HOLES
摘要:
A film-cooled turbine structure is configured with one or more asymmetric chevron film cooling holes for improving film cooling for a variety of airfoil surfaces or airfoil regions, particularly in regions and applications where the surface fluid streamline curvature is significant.
