We have constructed mathematical models on effects where phase transitions and hydrodynamics are coupled. We have then performed numerical simulations on the basis of these models. Coarse-grained phenomenological models and microscopic molecular dynamics models have both been used, depending on the nature of the problems. We have treated dynamics of wetting layers with evaporation and condensation, phase separation in aqueous mixtures induced by selective impurities, colloid interactions in aqueous mixtures, glass transition dynamics in anisotropic molecular systems, and liquid crystal dynamics in porous media. We have published a number of papers on these problems in journals with referees, but we are still working on these problems.

我们已经建立了数学模型的相变和流体力学耦合的影响。然后，我们进行了数值模拟的基础上，这些模型。粗粒度的唯象模型和微观分子动力学模型都被使用，这取决于问题的性质。我们已经处理了动态的润湿层蒸发和冷凝，相分离诱导的选择性杂质，胶体在含水混合物中的相互作用，各向异性分子系统的玻璃化转变动力学，在多孔介质中的液晶动力学的含水混合物。我们已经在期刊上发表了一些关于这些问题的论文，但我们仍在研究这些问题。
