A reaction turbine capable of providing unidirectional rotation under a reversible fluid flow is disclosed. The turbine comprises inflow and outflow fluid channels, a turbine chamber, and a working wheel with a plurality of airfoil-shaped blades mounted transversely to the direction of fluid flow for rotation in a plane parallel to the fluid flow. A channel directs the fluid flow to the blades. In the turbine chamber, the channel has a curved configuration having opposed changes in elevation or bulges directed towards the center of the turbine in a plane parallel to the flow of fluid to optimize the angle of attack of the fluid on the blades. In one embodiment, the channel also has a V or other linear or non-linear shape in transverse cross-section in the turbine chamber to smooth and direct the fluid flow. In another embodiment, the blades have a delta or other curvilinear shape, which smooths and directs the fluid flow and allows the channel to have a simpler rectangular cross-section. The turbine is capable of achieving high speeds at which electric generators conventionally operate and is suitable for use in hydro-pneumatic, hydro, wind, or wave power systems.
