PROBLEM TO BE SOLVED: To provide a vessel having turbulence generated by at least one or a plurality of turbulence generation devices installed on a surface of a hull, reducing thickness of a boundary layer on the surface of the hull, increasing pressure in stern by deviating a separation point to the rear and reducing resistance force when navigating.SOLUTION: A vessel 1 has a front end 110 and a terminal end 140 and can navigate in water flow. A central line is formed in between a bottom unit of the front end 110 and a bottom unit of the terminal end 140 of the vessel 1. A structure for reducing resistance force when the vessel 1 navigates has at least one turbulence generation device 2. The turbulence generation device 2 is installed on a surface in between a maximum width position 120 and the terminal end 140 on both sides of the vessel 1. A structure for reducing resistance force when the vessel 1 navigates further includes the plurality of turbulence generation devices 2.SELECTED DRAWING: Figure 7
【課題】船殻の表面に設置した少なくとも1つ又は複数の乱流発生装置により乱流を発生させ、船殻表面の境界層の厚さを減らし、分離点を後方へずらして船尾の圧力を高める、航行する際の抵抗力を減らす船舶を提供する。【解決手段】船舶1は、前端110及び末端140を有し、水流体中で航行することが可能である。船舶1の前端110の底部と末端140の底部との間には、中心線が形成される。船舶1が航行する際の抵抗力を減らす構造は、少なくとも1つの乱流発生装置2を有する。乱流発生装置2は、船舶1の両側の最大幅個所120と末端140との間の表面上に設置される。船舶1が航行する際の抵抗力を減らす構造は、複数の乱流発生装置2をさらに備える。【選択図】図7
