Abstract:
A generator stator core assembly is disclosed. The assembly includes a plurality of packages of stacked laminations, each package including an outermost lamination having a plurality of radially extending spacer blocks. The plurality of radially extending spacer blocks and adjacent axially spaced laminations define a radial cooling duct, and the outermost lamination includes a plurality of recesses such that a flow through the cooling duct flows over the plurality of recesses. In one embodiment, at least one adjacent axially spaced lamination defining the radial cooling duct also includes a plurality of recesses.

Abstract:
A jet impingement array design and method are disclosed for efficiently cooling the liner of a gas turbine combustion chamber, while eliminating almost all effects of coolant gas crossflow. The design includes an array of extended jet ports for which the distance between the ends of the jet ports and the surface to be cooled progressively decreases from upstream to downstream. Spent air from upstream jets is directed away from downstream jets, thereby reducing the detrimental effects of crossflow, and optimizing heat transfer.
