我们报告了模型多孔介质内包含的二元液体混合物中域生长和润湿动力学的计算机模拟结果，该模型多孔介质具有类似于 Vycor 玻璃的互连且曲折的结构。我们发现，当域的平均尺寸与平均孔隙半径相当时，生长过程会急剧减慢，并且动态缩放在后期会崩溃。我们认为不能调用随机场模型来解释这些结果。另一方面，单孔模型似乎相当成功地解释了这种缓慢增长的根源。
We report results from computer simulations of the kinetics of domain growth and wetting in a binary liquid mixture contained inside a model porous medium which has an interconnected and tortuous structure resembling Vycor glass. We find that the growth process slows down dramatically when the average size of the domains is comparable to the aver-age pore radius and dynamical scaling breaks down at late stages. We argue that the random-field model cannot be invoked to explain these results. On the other hand, the single-pore model seems to be reasonably successful in explaining the source of this slow growth.
