OCEAN CURRENT POWER GENERATING APPARATUS USING DUAL DUCTS PRODUCING BOUNDARY LAYER CONTROL EFFECT

摘要

PROBLEM TO BE SOLVED: To provide an ocean current power generation apparatus with more preferable power generation efficiency.SOLUTION: A power generating unit includes a turbine 110; an inner duct 120; and an outer duct 130. The turbine 110 includes a shaft box. The turbine 110 is located inside the inner duct 120. An outer diameter of an inflow side of the inner duct 120 is less than an outer diameter of an outflow side of the inner duct 120. The outflow side of the inner duct 120 is located inside the outer duct 130. An outer diameter of an inflow side of the outer duct 130 is less than an outer diameter of an outflow side of the outer duct 130.
