ABSTRACT:
A turbine airfoil includes sidewalls extending between leading and trailing edges, with an internal cooling circuit therein. A row of venturi slots commences inside the airfoil at the cooling circuit and terminates near the trailing edge. Each of the venturi slots includes an inlet, converging portion, throat, diverging portion, and outlet in serial flow communication from the cooling circuit. The converging portion is comparable in chordal length with the throat.
