The invention relates to the technical field of ship design and manufacturing, in particular to a ship sailing drag reduction device. In the sailing process of a ship, pumped gas and water are firstly guided into the primary mixing cavity and subjected to primary preliminary mixing to generate a primary liquid bubble mixture, then the primary liquid bubble mixture is jetted towards the flow dividing disc, and after collision, the primary liquid bubble mixture is divided into the left secondary mixing sub-cavity and the right secondary mixing sub-cavity; a left secondary liquid bubble mixture and a right secondary liquid bubble mixture are generated through mixing and then jointly guided into a third-stage mixing cavity, and a third liquid bubble mixture is generated through mixing. Due to multiple times of mixing, bubbles contained in the three-time liquid bubble mixture are finer in form and more compact in distribution. And in the mixing process of the high-pressure gas and the high-pressure water body, the generation process of the bubbles is mainly influenced by the turbulence effect instead of purely relying on the modification of the design structure of the ship body, so that the dependence on the water quality condition and the navigation speed is eliminated.

    本发明涉及船舶设计、制造技术领域,尤其是一种船舶航行减阻装置。在船舶航行进程中,被泵入的气体和水体首先被导流至一级混合腔中,经历一次初步混合以生成一次液泡混合体,而后向着分流盘进行喷射,且经历碰撞后被分流至左置二级混合子腔和右置二级混合子腔中,经历混合以生成左置二次液泡混合体和右置二次液泡混合体,而后共同被导流至三级混合腔中,经历混合以生成三次液泡混合体。因经历多次混合,三次液泡混合体中所包含气泡的形态更为细腻,且分布更为致密。且在高压气体和高压水体的混合进程中,气泡的生成进程主要受到湍流效应的影响,而非单纯地依靠船体设计结构的改型来实现,从而解除了对水质条件和航行速度的依赖。
