中文摘要
通过大规模的数值模拟,研究了湍流中长链聚合物分散的统计和动力学性质。在各向同性湍流的情况下,阐明了聚合物拉伸涨落的卷曲-拉伸转变的统计。我们发现,这种性质对由聚合物模型组成的微珠数量的变化不敏感。我们还讨论了聚合物拉伸动力学的时间尺度与速度梯度起伏的关系。
英文摘要
We investigated the statistical and dynamical nature of long chain polymers dispersed in turbulent flows by using the large-scale numerical simulations. Statistics of coil-stretch transition of polymer extension fluctuations was clarified in the case for isotropic turbulence. We found that this nature was insensitive to the variation of number of beads consisting of the polymer model. We also discussed the relationship between the time scale of polymer extension dynamics and velocity gradient fluctuations.
