Ocean current power generating apparatus using dual-duct with boundary layer control effect

Abstract

An ocean current power generating apparatus using dual-duct with boundary layer control effect is provided. The ocean current power generating apparatus with dual-duct includes at least one power generating unit. The power generating unit includes a turbine, an inner duct and an outer duct. The turbine has a shaft box. The turbine is located inside the inner duct. An outer diameter of an inflow side of the inner duct is less than an outer diameter of an outflow side of the inner duct. The outflow side of the inner duct is located inside the outer duct. An outer diameter of an inflow side of the outer duct is less than an outer diameter of an outflow side of the outer duct.
