论文摘要
使用分子模拟和经典的经典成核理论，我们研究了各种液体的成核，流动：不同的水模型，Lennard-Jones和硬球胶体。我们的方法使我们能够分析蛮力模拟无法访问的广泛的剪切速率。我们的结果表明，剪切成核速率的变化是通用的。该理论的简化版本成功地捕获了成核行为的非单调温度依赖性，这表明源自违反Stokes-Einstein关系。
Using molecular simulations and a modified Classical Nucleation Theory, we study the nucleation, under flow, of a variety of liquids: different water models, Lennard-Jones and hard sphere colloids. Our approach enables us to analyze a wide range of shear rates inaccessible to brute-force simulations. Our results reveal that the variation of the nucleation rate with shear is universal. A simplified version of the theory successfully captures the non-monotonic temperature dependence of the nucleation behavior, which is shown to originate from the violation of the Stokes-Einstein relation.
