Beschreibung
Zusammenfassung:	A turbine airfoil includes sidewalls extending between a leading edge and a trailing edge (44), with an internal cooling circuit (46) therein. A row of venturi slots (48) commences inside the airfoil at the cooling circuit and terminates near the trailing edge. Each of the venturi slots (48) includes an inlet (48a), converging portion (48b), throat (48c), diverging portion (48d), and outlet (48e) in serial flow communication from the cooling circuit. The converging portion is comparable in chordal length with the throat.
