A turbine engine with an outer rotor that circumscribes an inner rotor. The outer rotor includes circumferentially arranged components with a radial outer end and radial inner end. Inner ends of confronting sides of adjacent components include at least one damper element to dampen the relative motion of the components or to provide at least a partial seal between adjacent components.

A steam turbine includes a guide member that is disposed between a first rotor blade row and a second stator vane row to guide a fluid from the first rotor blade row toward the second stator vane row. When seen in a circumferential direction, an outer peripheral surface of an inner ring of the second stator vane row is disposed farther to an inner side in a radial direction than an outer peripheral surface of a platform of the first rotor blade row. The guide member has a guide surface that extends from an outer peripheral surface of a shroud of the first rotor blade row toward an inner peripheral surface of an outer ring of the second stator vane row so as to be inclined toward the inner side in the radial direction as the guide surface approaches a second side from a first side in an axial direction.

The present invention generally relates to high g-field combustion methods and integrated processes requiring high-energy efficiency and low NOx emissions to maximize fuel productivity and integrated process production output. In one embodiment, the present invention relates to the combustor having a g-field greater than 100,000 g's in an isothermal configuration by achieving concurrent combustion and expansion with the high g-field combustor in a rim-rotor turbomachine.

Disclosed are an impulse turbine and a turbine device. The disclosed impulse turbine includes a cylindrical body having an axial hole, and a blade unit arranged to surround the periphery of the body. The blade unit includes a cylindrical base arranged to surround the periphery of the body, and a plurality of unit blades radially arranged in a line along the periphery of the base. Each of the unit blades includes an outlet that discharges fluid, injected onto the unit blade, in a direction different from the fluid spray direction, but does not discharge the fluid toward the other unit blades.

Provided is a steam turbine in which, among a plurality of stages thereof, a stage that is disposed furthest upstream is a speed-adjusting stage, at least one stage that is disposed downstream of the speed-adjusting stage is a medium-pressure stage, and at least one stage that is disposed downstream of the medium-pressure stage is a low-pressure stage. The speed-adjusting stage is an impulse stage. The medium-pressure stage is a medium reaction degree impulse stage in which the degree of reaction is a medium degree of reaction of 10-40%. The low-pressure stage is a reaction stage having a higher degree of reaction than the medium-pressure stage.

The present application provides a turbine with a flow of steam therethrough. The turbine may include a first guide blade, a second guide blade, a flow path for the flow of steam therebetween, and a fluidic flow control device. The fluidic flow control device may include a bypass line for a portion of the flow of steam and an injection port for injecting the portion of the flow of steam into the flow path.
