摘要： PROBLEM TO BE SOLVED: To provide a rotor and an assembly for reducing a leakage flow.SOLUTION: In a rotary machine such as a steam turbine, pressurized fluid flows through a series of stationary and rotary components. Minimizing the leakage flow of the fluid enhances the operation and efficiency of the machine. At least one rotor land 240 has a groove 245 formed thereon to generate a vortex as the fluid passes over. The vortex resists the axial flow of the fluid, which reduces the leakage flow. The shape of the groove 245 formed on at least one rotor land 240 can be configured to be different from that of the groove 245 formed on at least one other rotor land 240.

摘要： PROBLEM TO BE SOLVED: To provide a diffuser shape within an exhaust hood, concerning the exhaust hood for condensing steam turbines.SOLUTION: Tip shrouds on last stage buckets 419 for condensing steam turbines 410 can create significant blockage and form a vortex at the wall of the steam guide 423, 424 of the diffuser, causing the steam flow to separate from the wall of the steam guide. Vortex formation reduces the effective flow area for the remaining fluid to diffuse, causing poor recovery. An inward radial depression 425 is provided of a predetermined depth and distance along steam guides 423, 424 inner wall 480, which redirects the tip leakage flows slightly downward, reducing a shroud blockage effect.
