The cross-flow turbine machine provides shaft power by extracting energy from a moving fluid. The fluid comprises both liquids and gases. Fluid is guided into the rotor by inlet guide means. The fluid then flows through the first rotor, through the interior, through the second rotor, through the exit, and through the diffuser to exit the machine at ambient pressure. Due to the change in angular momentum of the fluid across the turbine rotor, a torque is applied to the output power shaft. The output power shaft can be used, for example, to drive a water p...


A cross-flow turbine machine for extracting kinetic energy from a fluid to provide for shaft power output; the machine is comprised of: a. a cylindrical vaned rotor with axis of rotation perpendicular to the incoming flow; b. inlet housing for controlling the fluid velocity vector into the inlet rotor vanes; c. inlet guide vanes which curve in the direction of rotor rotation for controlling the flow velocity vector into the inlet rotor vanes; d. flow controlling means consisting of housing shapes around the rotor outer periphery, vortex forming means, ex...
