Abstract
The Cellular Potts Model (CPM) successfully simulates drainage and shear in foams. Here we use the CPM to investigate instabilities due to the flow of a single large bubble in a dry, monodisperse two-dimensional flowing foam. As in experiments in a Hele-Shaw cell, above a threshold velocity the large bubble moves faster than the mean flow. Our simulations reproduce analytical and experimental predictions for the velocity threshold and the relative velocity of the large bubble, demonstrating the utility of the CPM in foam rheology studies.
摘要
细胞Potts模型（CPM）成功地模拟了泡沫中的排水和剪切现象。在此，我们使用CPM来研究在干燥、单分散的二维流动泡沫中单个大泡流动所导致的不稳定性。如同在Hele-Shaw细胞实验中一样，超过阈值速度时，大泡的移动速度比平均流速快。我们的模拟再现了关于速度阈值和大泡相对速度的分析和实验预测，证明了CPM在泡沫流变学研究中的实用性。
