本文用晶格玻尔兹曼方法模拟了具有完全流体力学的二元流体混合物的三维稳态剪切。与某些理论情况相反，在所有三个空间方向上，获得具有有限相关长度的动态稳态。使用大型模拟，我们获得了在中等高雷诺数下的明显缩放指数，与我们之前在二维（2D）中发现的指数相当。然而，在3D中，在低雷诺数下可能存在不同行为的交叉：访问该区域需要比这里使用的更大的计算资源。
We simulate by the lattice Boltzmann method the steady shearing of a binary fluid mixture with full hydrodynamics in three dimensions. Contrary to some theoretical scenarios, a dynamical steady state is attained with finite correlation lengths in all three spatial directions. Using large simulations, we obtain at moderately high Reynolds numbers apparent scaling exponents comparable to those found by us previously in two dimensions (2D). However, in 3D there may be a crossover to different behavior at low Reynolds number: accessing this regime requires even larger computational resources than used here.
