Abstract : An airfoil is designed for use in an axial flow compressor, a high-bypass turbofan or as a turning vane in an airflow duct having a crenelated trailing edge. The crenelated trailing edge produces pairs of counterrotating vortices which promote rapid mixing between the low momentum fluid, in the wake of the airfoil, and the adjacent fluid streams. The mixing of the adjacent streams with the low momentum wake acts to re-energize the wake.
