The invention discloses a novel annular propeller structure based on gas-liquid two-phase flow, relates to the technical field of gas-liquid two-phase flow propulsion, and solves the problem of low propulsion efficiency of a traditional underwater propeller. The propeller comprises a propeller head, a propeller tail, an air distribution filter screen and a converter, a liquid inlet is formed in one end of the propeller head, the other end of the propeller head is connected with the propeller tail to form a propeller body, and a liquid outlet is formed in the other end of the propeller tail; a converter is arranged in the propeller main body; an air distribution filter screen is arranged in the front section of the tail part of the propeller; an air inlet is formed in the propeller head and is communicated with the inner side of the propeller tail; and an outlet of the air inlet is divided into two parts by the air distribution filter screen. Through mixing of liquid and high-pressure gas, high-energy two-phase flow is sprayed out from the tail, and thrust larger than that of a conventional pump-jet propeller is generated; due to the fact that no propeller exists, the influence of the cavitation erosion phenomenon is greatly reduced, and the performance of the thruster is effectively improved.
本发明公开了一种基于气液两相流的新型环形推进器结构,涉及气液两相流推进技术领域,解决了传统水下推进器推进效率低的问题。本发明包括推进器头部、推进器尾部、分气滤网和变流器,推进器头部一端设置有进液口,另一端和推进器尾部连接构成推进器主体,推进器尾部另一端设置有出液口;推进器主体内部设置有变流器;推进器尾部的前段内部设置有分气滤网;推进器头部上设置有进气口,进气口和推进器尾部内侧连通;分气滤网将进气口的出口分成两部分。本发明通过液体与高压气体的混合,在尾部喷出高能量的两相流,产生要比常规泵喷推进器更大的推力;由于不存在螺旋桨,空蚀现象的影响也大大下降,有效提高了推进器的性能。
