摘要：
建立了一种方法，用于建模和模拟具有任意相图的两相三元液体的畴粗化动力学。通过使用相场法进行界面捕捉、格子玻尔兹曼方法数值格式求解所有模型方程，以及在多个GPU上运行的可移植并行模拟代码，获得了较高的数值性能。该模型以三元扩散偶的解析解为基准进行了验证。它还再现了无流体流动时奥斯特瓦尔德熟化过程中液滴粗化的著名幂律。含流动的大规模模拟展示了动量输运和浮力效应，以及液滴聚并和沉降。
英文摘要：
A methodology is built to model and simulate the dynamics of domain coarsening of a two-phase ternary liquid with an arbitrary phase diagram. High numerical performance is obtained through the use of the phase field-method for interface capturing, a lattice Boltzmann method numerical scheme for all the model equations, and a portable, parallel simulation code running on multiple GPUs. The model is benchmarked against an analytic solution for a ternary diffusion couple. It also reproduces the well-known power law for droplet coarsening during Ostwald ripening without fluid flow. Large-scale simulations with flow illustrate the effects of momentum transport and buoyancy, as well as droplet coalescence and sedimentation.
