晶液界面剪切熔化:侵蚀和界面波动的非对称抑制

Shear Melting at the Crystal-Liquid Interface: Erosion and the Asymmetric Suppression of Interface Fluctuations

Malcolm Ramsay, Peter Harrowell

摘要:

平面晶体-熔体界面上施加的剪切的影响建模的非线性随机偏微分方程的界面波动。该理论的一个特点是界面波动的不对称破坏,由于对流的晶体突起的液体侧的界面上的唯一。我们表明,该模型是能够定性地重现在模拟中发现的非平衡共存线。剪切对球形团簇的影响也得到了解决。

英文摘要:

The influence of an applied shear on the planar crystal-melt interface is modelled by a nonlinear stochastic partial differential equation of the interface fluctuations. A feature of this theory is the asymmetric destruction of interface fluctuations due to advection of the crystal protrusions on the liquid side of the interface only. We show that this model is able to qualitatively reproduce the nonequilibrium coexistence line found in simulations. The impact of shear on spherical clusters is also addressed.
