Abstract

Systems and methods relate to utilizing fluid potential energy to produce large scale and sustainable hydroelectric power by employing a Cho-Venturi hydraulic ram (CVHR). The CVHR system includes a Cho-Venturi tube (CVT) in which a primary flow from a fluid at a head pressure at a depth in a body of the fluid combines with a recirculation flow in a throat section of the CVT. A pressure higher than the pressure outside the plant is generated at the end of a diverging section the CVT, which enables expulsion of the fluid discharged from hydraulic turbines under atmospheric pressure to the fluid depth while another portion of the fluid is recycled for power generation.
