A system for reducing resistance on a marine vessel (2), the system comprising: a plurality of outlets (4) provided in a hull of the vessel (2) for conveying a layer of air bubbles between at least a portion of the hull and water; at least one venturi tube (6) adapted to supply air and water to one or more of the plurality of air outlets (4); at least one seawater inlet (8), located in the bow region of the vessel (2), adapted to supply seawater to the at least one venturi tube (6) as the vessel moves through the water; at least one seawater pump (10) adapted to supply seawater to the at least one venturi tube (6); at least one ambient air inlet port (16) adapted to supply ambient air to the at least one venturi tube (6) such that the ambient air is entrained into the seawater flowing through the at least one venturi tube (6); a compressor (18) that supplies compressed air to the at least one venturi tube (6); and a controller adapted to adjust the flow rate of seawater supplied from the at least one seawater pump, and adapted to adjust the supply of compressed air from the compressor to optimize the delivery of air bubbles through the plurality of outlets in the hull, thereby optimizing the drag reduction of the vessel.
一种用于减少海洋船舶(2)上的阻力的系统,该系统包括:多个出口(4),多个出口(4)设置在船舶(2)的船体中,用于在船体的至少一部分与水之间输送空气气泡层;至少一个文丘里管(6),至少一个文丘里管(6)适于向所述多个空气出口(4)中的一个或更多个空气出口供应空气和水;至少一个海水入口(8),至少一个海水入口(8)位于船舶(2)的船头区域中,适于在船舶移动穿过水时向至少一个文丘里管(6)供应海水;至少一个海水泵(10),至少一个海水泵(10)适于向至少一个文丘里管(6)供应海水;至少一个环境空气入口端口(16),至少一个环境空气入口端口(16)适于向至少一个文丘里管(6)供应环境空气,使得环境空气被夹带到流动通过至少一个文丘里管(6)的海水中;压缩机(18),该压缩机(18)向至少一个文丘里管(6)供应压缩空气;控制器,该控制器适于调节从至少一个海水泵供应的海水的流量,并且适于调节来自压缩机的压缩空气的供应,以优化空气气泡通过船体中的多个出口的输送,从而优化船舶的减阻。
