A turbine airfoil (12) includes an internal cooling circuit (34) between opposite pressure and suction sidewalk (22,24). The pressure sidewall (22) includes a row of outlet slots (36) for the circuit (34) separated by converging partitions (38). Each slot (36) includes an inlet (40), throat (42), and diverging outlet (44). Each of the partitions (38) includes a step (46) in a converging sidewall thereof for increasing divergence of the slots to diffuse coolant discharged therethrough. |
