在受奴役的相分离前沿尾流中形成的螺旋位错畴的流体动力学录象

Fluid dynamics video of domains with spiral dislocations formed in the wake of an enslaved phase-separation front

E. M. Foard, A. J. Wagner

摘要:

以仅小于自由锋的速度移动的受控相分离锋将在其尾流中留下与锋大致对齐的交替畴的形态。然而,这些交替的畴通常最初将不同相。相反,存在缺陷。在这里,我们提出了新的相分离的形态,形成在这样的系统中的缺陷是让人想起螺旋位错在晶体生长。

英文摘要:

Enslaved phase-separation fronts that move with a speed just smaller than that of a free front will leave in their wake a morphology of alternating domains that are roughly aligned with the front. However, these alternating domains will typically not be in phase initially. Instead there are defects. Here we present novel phase-separation morphologies that are formed in such systems where the defects are reminiscent of spiral dislocations in crystal growth.
