    Abstract: A system includes a fluid distribution system. The fluid distribution system includes multiple spray rings disposed upstream of an inlet of a compressor. The multiple spray rings include a first spray ring disposed about an axis of the compressor in a first plane substantially perpendicular to the axis. The first spray ring includes a first set of nozzles disposed about the axis and configured to spray a first fluid flow toward the compressor inlet. The multiple spray rings further include a second spray ring disposed about the axis of the compressor in a second plane substantially perpendicular to the axis. The second spray ring includes a second set of nozzles disposed about the axis and configured to spray a second fluid flow toward the compressor inlet. The first plane is different than the second plane.

    Abstract: Stator vanes including curved trailing edges are disclosed. The stator vanes may include a body including a central section, a tip section positioned radially above the central section, and a root section positioned radially below the central section. The body of the stator vanes may also include a leading edge extending radially adjacent the root section, central section, and tip section, respectively, and a trailing edge positioned opposite and aft to the leading edge. The trailing edge may include a concave contour including a first portion radially aligned with the central section of the body. The first portion may be axially offset and forward of a reference line that may be perpendicular to an axial direction and intersects the concave contour at the tip section and the root section. A concavity of the first portion of the concave contour may be formed radially aft of the central section.

    Abstract: A system is provided, including an airfoil. The airfoil includes a first suction portion of a nominal airfoil profile substantially in accordance with Cartesian coordinate values of X, Y, and Z of a suction side as set forth in TABLE I to a maximum of three decimal places, wherein the X and Y values of the suction side are coordinate values that couple together to define suction side sections of the first suction portion of the nominal airfoil profile at each Z coordinate value, the suction side sections of the first suction portion of the nominal airfoil profile are coupled together to define the first suction portion, the airfoil includes an airfoil length along a Z axis, the first suction portion comprises a first portion length along the Z axis, the first portion length is less than or equal to the airfoil length, and the Cartesian coordinate values of X, Y, and Z are non-dimensional values convertible to dimensional distances.
