摘要： A submerged flow augmented shrouded turbine power generation system with a forward flow compression section (11) and an aft multi-finned diffuser section (14) with a centrally supported generator (12) powered by turbine blades (15) optimized to be driven by the enhanced flow field created by the forward cowl and aft diffuser/fin sections. The system can be positively buoyant and tethered to the seafloor (18) or negatively buoyant and tethered to the underside of a vessel or offshore structure, or it can be attached directly to the underside of a vessel or offshore structure. An array of such systems can be placed on the seafloor to create a distributed power generation network. An array of such systems can also be placed on the seafloor to directly pump seawater to an energy storage device or a central desalination plant.

摘要： An improvement for a wave energy converter comprises a substantially rigid skirt (10) adapted to be suspended from a wave energy converter below the surface of the water. The skirt (10) comprises an elongate substantially cylindrical structure (12) extending vertically so as to form a flow path for water particles over a surface of the structure. The cylindrical structure (12) comprises a series of rings (14) of substantially equal diameter arranged concentrically at spaced vertical intervals. The curved surfaces formed by the circular cross-section of the rings (14), form an undulating flow path for water particles travelling in a vertical direction. In this way the vertical component of the wave energy extracted from the wave's circular water particle motion can be maximised.

摘要： The invention relates to a rotor blade (20) for a wind turbine (10), wherein the rotor blade (20) comprises serrations (30) along at least a portion of the trailing edge section (23) of the rotor blade (20). The serrations (30) comprise a first tooth (31) and at least a second tooth (32), and the first tooth (31) is spaced apart from the second tooth (32). The area (35) between the first tooth (31) and the second tooth (32) is at least partially filled with porous material such that generation of noise in the trailing edge section (23) of the rotor blade (20) is reduced. Furthermore, the invention relates to a wind turbine (10) comprising at least one such a rotor blade (20).

摘要： The surface (12) of a body (10) immersed in a fluid flow has projections (14) on the base surface. In order to design a more flow-favourable surface (12) of a body (10) immersed in a fluid flow and having projections (14) on the base surface, the projections (14) are surrounded by two demarcation lines (18, 20), as seen from above the surface (12). The first demarcation line (18) is longer and more curved than the other demarcation line (20), so that the projections (14) have the cross-sectional area of an airfoil.
