The invention provides a flow guiding device of a ship propeller and a ship. The flow guide device comprises a plurality of guide vanes, the guide vanes are fixedly connected to the stern of the ship in the circumferential direction of the propeller, and the guide vanes are arranged at different positions in the axial direction of the propeller. The guide vanes are arranged at different positions in the axial direction of the propeller, so that the stress borne by the flow guide device is reduced; by limiting the circumferential length of flow guide, the resistance borne by the flow guide device can be reduced on the premise that the stability of the structure is improved. The ship stern and the flow field around the propeller are improved, the propelling efficiency of the propeller is improved, and the pressure at the blade backs of the propeller blades can be increased, so that the stress of the propeller is increased, and the thrust component is increased accordingly; the flow field pressure at the guide vanes outside the guide wheel can be reduced, so that the flow velocity of the flow field is increased, and the propeller efficiency is improved.

    本申请提供一种船舶螺旋桨的导流装置及船舶。所述导流装置包括多个导叶,多个所述导叶绕螺旋桨的周向固定连接于船舶艉部,多个所述导叶设于螺旋桨的轴向上的不同位置处。本申请通过将导叶设于螺旋桨轴向的不同位置处,减小了导流装置所受应力;通过限制导流的圆周长度,在提高结构的稳定性的前提下,同时能够减小导流装置所受阻力。本申请改善了船舶艉部及螺旋桨周围流场,提高了螺旋桨推进效率,能够使螺旋桨叶片的叶背处压力增大,以使螺旋桨受力增大,从而使推力分量随之增大;能够减小导轮外侧导叶处的流场压力,从而使流场流速增大,提高了螺旋桨效率。
