Abstract
A diaphragm for an axial flow turbine includes a plurality of spaced apart nozzle partitions and an inner member for fixedly securing the nozzle partitions. The inner member is contoured to direct elastic fluid flow radially inward. The nozzle partitions are spaced such that a minimum throat extends a predetermined radial distance from the root, thereby forming a converging-diverging flow passageway between nozzle partitions. The trailing edge of the nozzle partitions are disposed to include axial and tangential lean with respect to the rotor of the turbine.
