A novel thermodynamically consistent lattice Boltzmann model that enables dynamical effects of two-phase fluids is developed. The key innovation is the application of the entropic lattice Boltzmann stabilization mechanism to control the dynamics at the liquid-vapor interface. This allows us to present a number of simulations of colliding droplets, including complex phenomena such as the formation of a stable lamella film. Excellent agreement of the simulation with recent experiments demonstrates the viability of the present approach to simulation of complex dynamic phenomena of multiphase fluids.
开发了一种新颖的、热力学上一致的格子玻尔兹曼模型，该模型能够实现两相流体的动力学效应。关键创新在于应用熵格子玻尔兹曼稳定机制来控制液-气界面处的动力学。这使我们能够给出许多碰撞液滴的模拟结果，包括诸如形成稳定的薄片膜等复杂现象。模拟结果与近期实验的出色吻合证明了本方法对于模拟多相流体复杂动态现象的可行性。
