Droplet supercooling in marine icing tests is studied theoretically using established correlations for convection and evaporation. The effect of freestream turbulence on heat and mass transfer is included through an empirical modification to the Nusselt and Sherwood numbers. Droplets are shown to cool following a modified exponential decay, with the trajectory length and shape determined by a thermal mixing length and a cooling exponent. The space needed for supercooling is shown to increase with (droplet diameter)^1.8, and also depend on wind speed, injection speed and ambient temperature. Turbulence at realistic offshore levels shortens cooling distances by up to 50%. A reanalysis shows that previous marine icing tests have typically reached supercooling higher than 80% of cooling potential for small droplets up to 100–200 μm, and possibly up to 300–400 μm in long setups at low wind speeds if boosted by turbulence or a contracting tunnel; larger droplets have been significantly undercooled compared to field conditions.

利用已建立的对流和蒸发相关性从理论上研究了海洋结冰试验中的液滴过冷。通过对努塞尔特和舍伍德数的经验修正，包含了自由流湍流对传热和传质的影响。液滴按照修正的指数衰减冷却，轨迹长度和形状由热混合长度和冷却指数决定。过冷所需的空间随着（液滴直径）^1.8的增加而增加，并且还取决于风速、注射速度和环境温度。实际海上水平的湍流可将冷却距离缩短高达 50%。重新分析表明，以前的海洋结冰测试通常会达到高于 100-200 μm 的小液滴冷却潜力的 80% 以上的过冷效果，如果在低风速下的长装置中，如果受到湍流或强风的推动，则可能达到 300-400 μm。承包隧道；与现场条件相比，较大的液滴明显过冷。
