    摘要： A combustor liner for a gas turbine includes a body having a plurality of angled strips on an outside surface of the combustor liner. The plurality of angled strips are arranged in an array about the outside surface. A space is disposed between each of said plurality of angled strips so as to create vortices in a cooling air flowing in a longitudinal direction across said outside surface of said combustor liner. A method of fabricating a combustor liner includes forming a plurality of angled strips on an outside surface of the combustor liner and arranged in an array about the outside surface, each of the angled strips is disposed so as to be spaced apart to create vortices in a cooling air flowing across the outside surface of the combustor liner.

    摘要： A turbine assembly includes a plurality of rotor blades comprising a root portion, an airfoil having a pressure sidewall and a suction sidewall, and a top portion having a cap. An outer shroud is concentrically disposed about said rotor blades, said shroud in combination with said tip portions defining a clearance gap. At least one circumferential shroud leakage discourager is disposed within the shroud. The leakage discourager(s) increase the flow resistance and thus reduce the flow of hot gas flow leakage for a given pressure differential across the clearance gap to improve overall turbine efficiency.

    摘要： In one embodiment, a system includes a sight tube configured to optically communicate with an interior of a rotary machine via insertion within an inspection port. The sight tube includes a window and multiple openings configured to direct purge air across the window. The system also includes a curtain tube disposed about the sight tube and configured to direct purge air from a first air source to the openings via a first passage formed between an inner surface of the curtain tube and an outer surface of the sight tube. The curtain tube includes multiple outlets configured to direct curtain air around the window, and the curtain tube is configured to direct the curtain air from a second air source to the outlets via a second passage formed between an outer surface of the curtain tube and an inner surface of the inspection port.
