The present invention provides an asymmetric fan-shaped stern duct for energy saving of a ship, which includes: a duct which is located on an upper part of a center line of a fan-shaped propeller shaft, and is installed to be asymmetric to a starboard side around a center line; and two pin structures which are installed to meet a left end and a right end of the duct by being spread to the direction of the duct at the center line of the propeller shaft. According to the present invention, the asymmetric fan-shaped stern duct can save energy of the ship through interaction between the fan-shaped duct and the pin structure, and more particularly, can improve hull resistance performance by rectifying and accelerating flow of a stern flowing field by operation of the duct, and can improve propeller propulsion performance through wake variation flowing into the propeller by operation of the pin structure, and furthermore, can improve propeller efficiency by making rotational flow in advance.

    본 발명은, 부채꼴 형상으로 프로펠러 축 중심선의 상부에 위치하되 센터라인을 기준으로 우현 방향으로 비대칭이 되도록 설치되는 덕트; 및 프로펠러 축 중심선에서 상기 덕트 방향으로 뻗어나가 각각 상기 덕트의 좌측 끝단 및 우측 끝단과 만나도록 설치되는 두 개의 핀구조물;을 포함하는 선박 에너지 절감을 위한 비대칭 부채꼴 선미 덕트를 제공한다. 본 발명에 따르면, 부채꼴 형상의 덕트와 핀구조물의 상호작용을 통해 선박의 에너지를 절감할 수 있는바, 보다 구체적으로는, 덕트의 작용으로 선미 유동장의 흐름을 정류하고 가속시킴으로써 선체 저항성능을 개선하고, 핀구조물의 작용으로 프로펠러에 유입되는 반류 변화를 통해 프로펠러 추진성능을 개선하며 나아가 미리 회전류를 만들어 프로펠러 효율을 개선할 수 있다.
