We investigate the thermal conductivity of liquid water using computer simulations of the TIP5P model of water. Our simulations show that, in addition to the maximum at high temperatures at constant pressure that it exhibits in experiments, the thermal conductivity also displays a minimum at low temperatures. We find that the temperature of minimum thermal conductivity in supercooled liquid water coincides with the temperature of maximum specific heat. We discuss our results in the context of structural changes in liquid water at low temperatures.
我们使用 TIP5P 模型水的计算机模拟来研究液态水的热导率。我们的模拟表明，除了实验中在恒压下高温时出现的最大值外，热导率在低温时也显示出最小值。我们发现过冷液态水中热导率最小值的温度与最大比热容的温度重合。我们在低温下水的结构变化的背景下讨论了我们的结果。
