Investigation of heat exchange mechanism between air and sea in a sea-wave tank

极地地区海冰的存在在世界气候系统中起着重要作用，因此了解影响冰原形成和变形的过程非常重要。本研究的目的是探讨在波浪场中，冰和油饼冰的热力学特性。我们使用了一个安装在冷室中的波浪槽来产生油饼冰。用红外热成像仪测量表面温度。结果表明，水温和波浪周期是决定冰生长和演变的重要因素。此外，饼周边的温度变得高于其中心的温度，这表明凝固热是当碎冰冻结到其周边时产生的。

The presence of sea ice in the polar regions plays an important role in the world's climate system, and it is therefore important to understand the process influencing the formation and deformation of ice fields. The objective of our research was to investigate characteristics of the thermodynamics of frazil and grease-pancake ice in a wave field. We used a wave tank installed in a cold room to generate grease-pancake ice. The surface temperature was measured by using an infrared thermography. We concluded that the water temperature and wave period are an important factor to determine the growing and evolving of frazil ice. Furthermore, the temperature of pancake periphery became higher than that of its center, which indicates that the heat of solidification is caused when the frazil ice froze to its periphery.
