Abstract:
A nozzle for a turbine, comprising:an array of partitions spaced circumferentially one from the other about an axis and between radially inner and outer end walls, each partition having a leading edge and a trailing edge, adjacent partitions having throat dimensions defined by the shortest dimension between convex and concave sides thereof;the trailing edge of each partition having first and second edge portions extending linearly;the throat dimension defined by said first trailing edge portion of each partition and said convex side of an adjacent partition at corresponding radial locations relative to said axis decreasing from said inner end wall in a radially outward direction to an approximate mid-span radial height, the throat dimension defined by said second trailing edge portion of each partition and said convex side of said adjacent partition at corresponding radial locations relative to said axis increasing from adjacent said approximate mid-span radial height to said outer end wall.
