我们提出了一个二维和三维格子玻尔兹曼模型的自由表面流动，包括气体扩散的治疗。界面平流和相关的边界条件是基于格子玻尔兹曼方程的思想。流体动力学边界条件通过使用穿过界面的质量和动量通量来近似，这不需要显式计算梯度。一个类似的过程是适用于满足扩散边界条件。简单的验证测试证明了算法的正确性。二维和三维泡沫演变的例子证明了该方法的潜力。
We present a 2D- and 3D-lattice Boltzmann model for the treatment of free surface flows including gas diffusion. Interface advection and related boundary conditions are based on the idea of the lattice Boltzmann equation. The fluid dynamic boundary conditions are approximated by using the mass and momentum fluxes across the interface, which do not require explicit calculation of gradients. A similar procedure is applied to fulfill the diffusion boundary condition. Simple verification tests demonstrate the correctness of the algorithms. 2D- and 3D-foam evolution examples demonstrate the potential of the method.
