摘　　要：水中气泡广泛应用于化工、环境及海洋等工程实践中,其动力学特性及与周围流体的相互作用是气液两相流领域研究的热点。本文分析了水中气泡的基础特性,以及少量存在的气泡对流场声学、光学等特性的影响,探讨了基于上述特性的舰船隔声降噪、舰船减阻、舰船尾流抑制等技术,可为水中气泡在船舶领域应用的进一步拓展提供参考。Bubble in water is widely used in many fields, such as chemical engineering, environment engineering and maritime engineering. Its hydrodynamic characteristic and mutual influence between bubble and surrounding water is key point of gas-liquid two-phase fields. In this paper, bubble basic characteristic and acoustics and optics property of bubbly liquid was analyzed. Applied technology in ship field based on these characteristics was discussed, including ship sound insulation and noise reduction by using gas bubble curtain, ship drag reduction and ship bubble wake control technology. The conclusion will be valuable to further develop bubble applications in ship and related fields.
