本文介绍了一种模拟二维不混溶二元流体的格子Boltzmann模型。该模型，格子气体流体动力学的玻尔兹曼方程的基础上，采用了以前介绍的离散不混溶格子气体模型的功能。的表面张力系数的理论值的推导和发现是在良好的协议从模拟获得的值。该模型作为一种数值方法，用于模拟不混溶的两相流;初步应用说明了在二维微观模型的多孔介质中的流动模拟。将模型扩展到三维似乎很简单。
We introduce a lattice Boltzmann model for simulating immiscible binary fluids in two dimensions. The model, based on the Boltzmann equation of lattice-gas hydrodynamics, incorporates features of a previously introduced discrete immiscible lattice-gas model. A theoretical value of the surface-tension coefficient is derived and found to be in excellent agreement with values obtained from simulations. The model serves as a numerical method for the simulation of immiscible two-phase flow; a preliminary application illustrates a simulation of flow in a two-dimensional microscopic model of a porous medium. Extension of the model to three dimensions appears straightforward.
