An airfoil (10) is provided and includes a body (20) formed to define a substantially radially extending cooling hole (30) therein, which is configured to be receptive of a supply of a coolant (11) for removing heat from the body (20), and a flag region (40) therein, which is fluidly communicative with the cooling hole (30) and thereby configured to be receptive of a portion of the supply of the coolant (11) such that the coolant portion is directed to form a vortex within the flag region (40) to increase heat removal from the body (20) beyond that provided by the coolant flow through the cooling hole (30). |
