Abstract [en]

An apparatus for generating electric power from water currents comprises a housing having at least one pair of channel, at least one pair of turbine assemblies and at least one pair of generator assemblies. Each channel of the pair has an axial intake, an axial discharge opening and a side intake. Each side intake extends along a length of the channel and faces in an upstream direction to receive a side inflow of water and directs the side inflow up against an interior surface of the channel to create a vortical flow structure having a low pressure core. The vortical flow structures are produced downstream of the turbine assemblies to effect an increase in a pressure drop across each of the turbine assemblies. The apparatus also has partition extending between the channels near said axial intakes.
