Abstract

In a device to generate power from flowing water, the water flows inside the host body (6) of the turbine and rotates the rotor (2), which rotates an electrical generator (10) to produce electricity. The Water Flow Turbine converts the kinetic energy in the flowing water into electrical energy. A mathematical derivation shows that power can be magnified by funnelling. This magnification of the power is proportional to the square of the ratio of the inlet area (1L or 1R) of the host body (6) to the area of the rotor (2) projected area. This magnification of power implies smaller size rotors, which reduce the cost and mechanical problems associated with rotation. Flow director (7) is used to direct the flow when reverses, instead of directing the whole underwater turbine. This device belongs to tidal power, and can work either for unidirectional flow or oscillatory flows.
