An improved cooling system for a gas turbine is disclosed. A plurality of V-shaped notch weirs are utilized to meter a coolant liquid from a pool of coolant into a plurality of platform and air foil coolant channels formed in the buckets of the turbine. The V-shaped notch weirs serve to desensitize the flow of coolant into the individual platform and air foil coolant channels to design tolerances and non-uniform flow distribution. |
