Abstract Sea spray icing poses a hazard for marine vessels in cold climates. This experimental study considers fresh and saltwater droplets in the inviscid, impact-driven regime solidifying on a variety of marine surfaces, coated and uncoated, under arctic conditions. A first order thermal resistance model is developed which includes the resistance within the post-impact drop and the transient spreading resistance within the substrates and coatings. An expression for dimensionless time-to-freeze based on thermal resistance is developed which shows good agreement across a wide range of dimensionless time. Notably, when the coating is a poor thermal conductor as is typical of marine coatings, the transient spreading resistance within the surface and coating significantly influences the post-impact spread radius and time-to-freeze. This study provides expressions to quantify the effects of substrate and coating thermophysical properties on the solidification process.

热传输对海水和淡水水滴在海洋表面固化的影响

摘要 海雾结冰对寒冷气候下的船舶构成危害。这项实验研究考虑了在北极条件下在各种海洋表面（有涂层和无涂层）上固化的无粘性、撞击驱动状态中的淡水和咸水液滴。开发了一阶热阻模型，其中包括冲击后滴内的电阻和基材和涂层内的瞬态扩散电阻。开发了一种基于热阻的无量纲冻结时间表达式，该表达式在很宽的无量纲时间范围内表现出良好的一致性。值得注意的是，当涂层是典型的船舶涂层的不良热导体时，表面和涂层内的瞬态扩散阻力会显着影响冲击后扩散半径和冻结时间。
