摘要： Close-coupled atomization systems and methods employing axisymmetric fluid flow and non-axisymmetric melt guide tube exit orifice configuration have demonstrated superior efficiency in the production of fine superalloy powder, such as, for example, nickel base superalloys compared to conventional close-coupled atomization utilizing an axisymmetric annular gas orifice and an axisymmetric guide melt guide tube exit orifice configuration.

摘要： A gas turbine rotor in the rim of which liquid cooled dovetailed buckets are mounted is provided with at least one coolant feed/retainer ring shrunk fit to the side of the rotor and exerting positive axial force solely by means of a reverse angle fit. The configuration of the ring is such that an annular gutter is formed therein having equally spaced outlet holes therefrom disposed around the circumference thereof. Each of these holes is in flow communication with and forms part of at least one open-ended liquid cooling circuit servicing either the pressure or the suction side of a given turbine bucket. The feed holes function to meter the liquid coolant entering the cooling circuits.
