The invention discloses a tail wave suppression body with fins, which is connected to a stern, is used for transmitting water power to a ship body, and comprises a tail wave suppression body top plate, a tail wave suppression body bottom plate, a toggle plate and the fins, the tail wave suppression body top plate is located on the upper side of the tail wave suppression body bottom plate, the tail wave suppression body top plate, the tail wave suppression body bottom plate and the tail sealing plate form a watertight floating body used for increasing the buoyancy of a stern, and the toggle plates are distributed and fixed in the watertight floating body to improve the strength of the watertight floating body. The fins are vertically distributed along the tail wave suppression body bottom plate for rectification, the front portions and the rear portions of the fins are connected to the lower side of the ship bottom plate and the lower side of the tail wave suppression body bottom plate respectively, and the rear edges of the tail wave suppression body top plate, the tail wave suppression body bottom plate and the fins are all located on the rear edge of the tail wave suppression body. The tail flow field is effectively adjusted, and the tail flow field adjusting device has the advantages that wake flow energy is recycled, tail wave making is reduced, energy conservation and resistance reduction are conducted on a ship, and wake flow noise is reduced.
本发明公开一种带鳍的尾压浪体,连接在船尾,用于将水动力传递到船体,包括尾压浪体顶板、尾压浪体底板、肘板和鳍;尾压浪体顶板位于尾压浪体底板上侧且二者与尾封板形成用于增加船尾浮力的水密浮体,肘板分布固定在水密浮体内用以提高水密浮体强度,尾压浪体底板与水平面成夹角且其前缘与尾封板底缘共形,鳍沿尾压浪体底板垂直分布用以整流,鳍的前后部分别连接在船底板和尾压浪体底板的下侧,尾压浪体顶板、尾压浪体底板和鳍的后缘均处于尾压浪体的后缘。本发明实现了对尾部流场的有效调节,具备回收尾流能量、减小尾部兴波、对船舶节能减阻、降低尾流噪声的优点。
