摘要
气幕系统是舰艇用来降低噪声辐射的一种有效手段。但由于水下喷气环突出在船体外,因此会对舰船性能造成影响。本文通过水池船模阻力试验,针对各种喷气环排列对阻力的影响和气液两相流对阻力的影响进行分析,同时,就其对航速的影响进行了讨论。
Bubble-screen system is often used to reduce the underwater noise radiation from naval ships. Because of air-liquid currents standing out the hull, the performance of naval ships get worse. The effect on the resistance caused by the arrangement of the air emitter belt, the appearance of bubble-screen and air-liquid currents have been discussed in this paper by means of the ship model experiment in the tank. The effect on the speed of a ship is also discussed.
