摘要： There is described a fluid flow concentrating device suitable, for example, for concentrating the flow of tidal waters or of wind, which comprises a hollow body closed at one end and open at the other. The body has a fixed circumferential wall composed of a plurality of fixed spaced vanes and a nozzle located at the open end of the wall. Fluid moving from outside the device through the vanes to the inside of the body creates a vortex within the body and a fluid flow axially of the body through the nozzle. In certain preferred embodiments a turbine is located for rotation in a direction opposite to the direction of rotation of the vortex about a vertical axis, centrally within the nozzle downstream of the fluid flow. The turbine can be used to drive a generator or a motor to, for example, propel a marine craft, or, the augmentor can be used on a aircraft to assist the lift of a wing, or, in another application, can be used with a jet turbine engine to improve both the intake to and the thrust from the engine.
