Abstract
一种舰船主机尾气它隐与自隐利用方法,其属于舰船隐身及对尾气循环利用技术的应用领域。本文创新性地提出利用舰船大量排放的尾气进行抑制尾流气泡数量,该技术将主机排放的尾气,经处理后,由水下进行排放,既可以将高温尾气进行红外及可视化隐身。又可以利用尾气施放的大量大气泡,通过与尾流微气泡聚并、携带、中和作用,对舰船尾流气泡产生有效的干扰,不断捕捉吸引尾流中的微气泡以较大浮力克服湍流的阻碍,迅速浮出水面,达到消尾流的作用。此法减少舰船空间占用,对船体结构改动小。更加贴近实际使用,是进行消尾流气泡是最简单直接的手段。为真正实现舰船气泡尾流抑制这一新技术的应用,提供更便捷的途径。此技术可以从根本上实现舰船的尾流气泡的消除,并具有启用迅速、结构布置灵活等优点,恰恰可以作为舰船主机尾气消除尾流技术。
The utility model relates to a method for concealment and self concealment of the tail gas of a ship's main engine, which belongs to the application field of the technology of ship stealth and exhaust gas recycling. This paper innovatively proposes to use the exhaust gas emitted by ships to suppress the number of wake bubbles. This technology treats the exhaust gas emitted by the main engine and discharges it underwater, which can make the high-temperature exhaust gas infrared and visualized stealth. In addition, a large number of large bubbles released by the exhaust can be used to effectively interfere with the wake bubbles of the ship by merging, carrying, and neutralizing the wake microbubbles, and continuously capture and attract the microbubbles in the wake to overcome with greater buoyancy. Obstructed by turbulent flow, it quickly surfaced and achieved the effect of eliminating wake flow. This method reduces the space occupied by the ship and makes little changes to the hull structure. Closer to the actual use, it is the simplest and most direct method to eliminate wake bubbles. In order to truly realize the application of this new technology of ship bubble wake suppression, a more convenient way is provided. This technology can fundamentally eliminate the wake bubbles of ships, and has the advantages of rapid activation and flexible structural arrangement.
