Sea Spray (MR16-06)

Marine disasters caused by ship icing occur frequently in cold regions. The typical growth mechanism of sea spray icing is as follows. First, sea spray is generated from the bow of the ship. Next, the spray drifts and impinges upon the superstructure, after which there is a wet growth of ice from the brine water flow. To address icing on the ship, we focus on the impinging seawater spray. We investigated the drop size of seawater spray and made sampling of superstructure ice accretion on R/V Mirai.

船舶积冰引发的海洋灾害在寒冷区域频发。海喷雾积冰（sea spray icing）的典型生长机理如下：首先，海喷雾由船舶船艏生成；随后，喷雾随气流漂移并撞击船舶上层建筑，继而通过盐水膜流形成湿态积冰。为应对船舶积冰问题，本研究聚焦于撞击式海水喷雾，对海水喷雾的液滴粒径开展了调查，并在未来号（R/V Mirai）科考船上采集了上层建筑积冰样本。
