A method for providing high cooling effectiveness over the entire length of a cooling path (20) by injecting supplemental coolant into the path (20) at one or more selected downstream locations (32,44).

A method for providing high cooling effectiveness over the entire length of a cooling path (20) by injecting supplemental coolant into the path (20) at one or more selected downstream locations (32,44). Optimal selection of the injection location (32,44) and the ratio of injected flow to main flow will provide a cooling design with superior temperature uniformity and reduced coolant consumption relative to non-supplemented cooling path designs.

[ What is claimed is:] [1.]1. A method of cooling a turbine comprising the steps of:providing a component for said turbine;forming a first cooling path through said component below a surface to be cooled, said first cooling path having an inlet end and an outlet end disposed remote from said surface

[ What is claimed is:] [1.]1. A method of cooling a turbine comprising the steps of:providing a component for said turbine;forming a first cooling path through said component below a surface to be cooled, said first cooling path having an inlet end and an outlet end disposed remote from said surface, said first cooling path including a cooling length disposed below said surface;forming a second cooling path through said component below said surface, said second cooling path having an inlet end and an outlet end disposed remote from said surface, said second cooling path outlet end being fluidly connected to said first cooling path at a junction located between the inlet end and the outlet end of said first cooling path along said cooling length;providing a first cooling fluid to the inlet end of said first cooling path and directing said first cooling fluid along said first cooling path;providing a second cooling fluid at the inlet end of said second cooling path and directing said second cooling fluid along said second cooling path to join said first cooling fluid at said junction point;directing said first and said second cooling fluids to the outlet end of said first cooling path.
