Abstract

一种降低舰船航行时兴波阻力和摩擦力的方法及装置，装置包括连接的气液混合装置（1）与控制装置（2），气液混合装置（1）设有进水口（62，721）、进气口（722，811）、出水口（63）以及设置于进水口（62，721）与出水口（63）之间的气液混合腔，水与气体分别经进水口（62，721）与进气口（722，811）进入气液混合腔内，控制装置（2）控制进气口（722，811）进气，并在此过程中控制进水口（62，721）间歇性地暂停进水或间歇性地低速进水或一直低速进水，从而更多气体进入气液混合腔内。气液混合装置（1）能生成含有大量气泡的气水混合物，向舰船前端或/和舰船两侧的水域注入气水混合物，降低水域的水密度，提高舰船航行速度以及舰船的机动性。
