给出了复杂流体剪切流动的数值模拟结果。我们采用了一种混合的方法，它结合了格子Boltzmann方法求解Navier-Stokes方程和对流扩散方程的有限差分格式。研究了剪切带现象随时间的演化。这是允许所提出的数值模型，考虑到局部结构的演变及其对流体流动的影响。
We present the numerical results of simulations of complex fluids under shear flow. We employ a mixed approach which combines the lattice Boltzmann method for solving the Navier–Stokes equation and a finite difference scheme for the convection–diffusion equation. The evolution in time of shear banding phenomenon is studied. This is allowed by the presented numerical model which takes into account the evolution of local structures and their effect on fluid flow.
