Abstract:
1. A turbine airfoil, comprising: pressure and suction sidewalls extending longitudinally in span from a root to a tip and having a first wall portion and a second wall portion, said sidewalls extending in chord between leading and trailing edges and being spaced laterally apart between said leading and trailing edges and joined together by a first partition extending longitudinally between said root and said tip to define a first flow passage and a second flow passage, said first and second flow passages for flowing coolant fluid therethrough; a plurality of cooling circuits disposed between said first wall portion and said second wall portion of said pressure sidewall, wherein each of said cooling circuits includes: a plurality of cooling circuits disposed between said first wall portion and said second wall portion of said suction sidewall, wherein each of said cooling circuits embedded within said suction sidewall includes: wherein said first flow passage is not in flow communication with said cooling circuits embedded within said suction sidewall and said second flow passage is not in flow communication with said cooling circuits embedded within said pressure sidewall such that said first flow passage feeds the coolant fluid to said cooling circuits that are embedded only within said pressure sidewall and said second flow passage feeds the coolant fluid to said cooling circuits that are embedded only within said suction sidewall.
