摘要： A compliant seal assembly for a rotating machine is provided. The seal assembly includes a static member, a movable member and a biasing member. The static member is rigidly fixed to the machine at its fore and aft ends. The movable portion has a first sealing surface configured to seal against a rotating member and a rear surface, which may be exposed to a fluid pressure to urge the first sealing surface toward a sealing position with the rotating member. The static and the movable members further include sealing surfaces at their fore, aft and end faces to seal against leakage of gas between the static and the movable members. The biasing member is configured to support the movable member on the static member and to urge the movable member away from the sealing position so as to reduce force on the rotating member during contact of the rotating member with the first sealing surface of the movable member.

摘要： An article having low wettability is presented. The article comprises a body portion and a surface portion disposed on the body portion. The surface portion comprises a plurality of features disposed on the body portion, and the features have a size, shape, and orientation selected such that the surface portion has a wettability sufficient to generate, with a reference liquid, a contact angle of at least about 100 degrees. The features comprise a height dimension (h) and a width dimension (a), and are disposed in a spaced-apart relationship characterized by a spacing dimension (b). The ratio of b/a and the ratio of h/a are such that the drop exhibits metastable non-Wenzel behavior.

摘要： An apparatus for the transfer of heat is presented. The apparatus comprises a textured heat transfer surface disposed to promote condensation of a vapor medium to a liquid condensate, the surface comprising a plurality of surface texture features disposed on the heat transfer surface. The plurality of features has a median size, a median spacing, and a median height displacement such that the force exerted by the surface to pin a drop of condensate to the surface is equal to or less than an external force acting to remove the drop from the surface. Also included are heat pumps, systems for power generation, and distillation systems comprising the apparatus.

摘要： A brush seal is provided between static components of a turbine. The turbine flowpath has an inlet spaced from another the inner web of the first stage nozzle. A brush seal is disposed between the two static components to minimize leakage flow to the packing casing region. The bristles of the brush seal are preloaded to fill any gap between the static components caused by distortion or out-of-roundness of the opposed surfaces being sealed. A side plate may contact the opposed sealing surface, increasing the pressure capability of the brush seal and minimizing overall seal leakage by providing the minimum possible flow area restricted solely by the bristles.

摘要： A shaft seal serves to reduce leakage between a rotating shaft and a static shell. The shaft seal includes a plurality of compliant plate members, each having a root and a tip. The compliant plate members are secured to the static shell at their root in facing relation. The tips of the compliant plate members define a sealing ring between the static shell and the rotating shaft. An axial flow resistance member is disposed within the compliant plate members and serves as a barrier to axial leakage flow between the compliant plate members.

摘要： The invention provides spray coatings to achieve circumferentially non-uniform seal clearances in turbomachines. In steam and gas turbines it is desirable to assemble the machines with elliptical seal clearances to compensate for expected casing distortion, rotordynamics or phenomena that cause circumferentially non-uniform rotor-stator rubs. The claimed invention allows the casing hardware to be fabricated round, and a spray coating is applied to the radially inner surface such that the coating thickness varies circumferentially, providing the desired non-uniform rotor-stator clearance during assembly.
