Abstract

A duct assembly for a cross-flow water turbine comprising two oppositely facing symmetrical ducts and a support assembly. Each duct comprises an active surface and a back surface. The active surface faces the turbine, protrudes away from the back surface, is symmetrical about a plane coplanar with the rotational axis of the turbine, and has an angle of attack at the leading and trailing edges of between 60 and 80 degrees. Each duct has a length of between 0.9 to 1.3 times the rotational diameter of the turbine and a width of between 0.35 to 0.6 times the rotational diameter of the turbine. The support assembly supports each duct such that the frontal width of the duct assembly is between 1.75 to 2.25 times the rotational diameter of the turbine.
