在本文中，使用基于自由能的格子玻尔兹曼（LB）模型求解3D Navier-Stokes（N-S）方程和Cahn-Hilliard（C-H）方程。在该模型中，使用具有 D3Q19 速度模型的 LB 方程来恢复连续性和 N–S 方程，而另一个具有 D3Q7 速度模型的 LB 方程用于求解 C–H 方程（Int. J. Numer. Meth. Fluids, 2008; 56:1653–1671）用于求解 3D C–H 方程。
In this paper, the 3D Navier–Stokes (N–S) equation and Cahn–Hilliard (C–H) equations were solved using a free‐energy‐based lattice Boltzmann (LB) model. In this model, a LB equation with a D3Q19 velocity model is used to recover continuity and N–S equations while another LB equation with D3Q7 velocity model for solving C–H equation (Int. J. Numer. Meth. Fluids, 2008; 56:1653–1671) is applied to solve the 3D C–H equation.
