A hydrodynamic electrification system that generates electricity from water moving from a high side to a low side and around a structure that divides the low side from the high side generally includes a water transport system that directs the water from the high side presenting a hydraulic head, over the structure, and to the low side. The system includes a power extraction system having a wheel that receives the water from said water transport system and a mounting system having a high side anchor that connects near an intake to the water transport system at the high side and having a low side anchor that connects to the power extraction system at the low side.

Various arrangements of a turbine for a rotating coalescer element of a crankcase ventilation system for an internal combustion engine are described. In some arrangements, the turbine is an impulse turbine, which is also known as a pelton turbine or a turgo turbine. The turbine is used to convert hydraulic power from a stream of pressurized fluid to mechanical power that is used to drive the rotating element. The turbine includes a non-wetting surface (e.g., an oleophobic or hydrophobic surface) that repels the pressurized fluid. The non-wetting surface may be achieved through plasma coating, fluoropolymer coating, micro-topography features, and the like. The non-wetting surface increases the power transmission efficiency from the stream of pressurized fluid to the turbine, thereby increasing the rotational speed of the rotating element compared to wettable surfaced turbines, which in turn increases the efficiency of the rotating element.

An oscillating water column (OWC) turbine and method of extracting energy therefrom is provided. The OWC turbine includes a shaft (101) rotatable about a central axis (103), and first and second ports (112, 114) disposed around the central axis. A flow passage (104) extends radially-inward from the ports and extends axially therebetween. Rotor blades (120) are coupled to the shaft, intersect the flow passage, and are offset from the central axis by a first distance. First guide vanes (116) intersect the flow passage and are disposed proximal the first port. The first guide vanes (116) include first and second stators (116a, b), the first stators (116a) being positioned between the first port (112) and the second stators (116b). Second guide vanes (118) intersect the flow passage and are disposed proximal the second port. The first and second guide vanes are offset from the central axis by a second distance that is greater than the first distance.

A turbine arrangement for a bi-directional reversing flow is provided. The turbine arrangement may include a rotor rotatably mounted to rotate about an axis of the turbine arrangement, and the rotor may have a plurality of rotor blades disposed circumferentially thereabout. A first set of guide vanes may be circumferentially disposed about the axis for directing the bi-directional reversing flow to and from the rotor blades via a first flow passaged defined by a first duct. A second set of guide vanes may be axially spaced from the first set of guide vanes and circumferentially disposed about the axis for directing the bi-directional reversing flow to and from the rotor blades via a second flow passage defined by a second duct. The guide vanes may be disposed at a greater radius than the rotor blades, such that the guide vanes are radially offset from the rotor blades.

A separation assembly comprises a housing, a jet that expels a fluid within the housing, and a turbine assembly positioned within the housing and positioned so as to be contacted by the fluid expelled from the jet. The fluid causes the turbine assembly to rotate about a center rotational axis within the housing. The turbine assembly comprises a first turbine portion and a second turbine portion that are separately formed from each other and attachable together. The first turbine portion comprises a plurality of first vanes and the second turbine portion comprises a plurality of second vanes.

An impulse turbine of a turbine device 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.

A separation assembly comprises a housing, a jet that expels a fluid within the housing, and a turbine positioned within the housing. The fluid causes the turbine to rotate about a center rotational axis within the housing. The turbine comprises a first axial end, a second axial end, and a plurality of vanes extending axially relative to the center rotational axis from the first axial end to the second axial end. The plurality of vanes defines axially-extending channels between each of the plurality of vanes. The first axial end comprises a radially-extending structure that axially blocks the flow of the fluid through the first axial end. The second axial end does not comprise any structure that axially blocks the flow of the fluid through the second axial end.
