Abstract:
A hydro turbine for extracting energy from an incompressible liquid, comprising:a housing having a cylindrical chamber with a circumferential side wall and opposed end walls, a smaller rectangular inlet and a larger rectangular outlet formed in said side wall in horizontally opposed relation;an inlet duct of smaller rectangular cross section having an interior connected in fluid communication with said smaller rectangular inlet, and an outlet duct of larger rectangular cross section having an interior connected in fluid communication with said larger rectangular outlet;a cylindrical runner rotatably enclosed in said chamber having an axis of rotation perpendicular to the flow of said incoming incompressible liquid and having a central cylindrical hub with a plurality of circumferentially spaced peripheral blades extending angularly outward therefrom in a direction opposite the direction of the incoming liquid;a power take-off shaft connected with said runner to rotate therewith and having opposed outer ends extending rotatably and sealingly through said end walls for connection to power generating means; anda circumferential segment of said chamber side wall and said runner central hub defining an arcuate flow passageway of rectangular cross section extending between said inlet and said outlet;said runner and said shaft being rotated by conducting said incompressible liquid through said inlet duct of smaller rectangular cross section and said smaller rectangular inlet to engage a plurality of said blades disposed in said flow passageway and discharging said liquid through said larger rectangular outlet and said outlet duct of larger cross section.
