Abstract
In this study, we propose a three-phase boiling lattice Boltzmann flux solver (TB-LBFS) based on phase field theory. The TB-LBFS is capable of achieving spontaneous nucleation in nucleate boiling and handling multiphase flow calculations with large density ratios, such as 1:1000. The source terms in the control equations of TB-LBFS can be freely added and solved, offering high flexibility for secondary development. Additionally, TB-LBFS addresses the limitation of previous phase field boiling models that could not achieve spontaneous nucleation. The model's excellent capability in simulating three-phase flow phase transitions has been tested through multiple classic 2D and 3D cases, including 2D composite droplet evaporation, the 2D Leidenfrost phenomenon, and 3D nucleate boiling in both two-phase and three-phase systems.
期刊介绍：
The International Journal of Multiphase Flow publishes analytical, numerical and experimental articles of lasting interest. The scope of the journal includes all aspects of mass, momentum and energy exchange phenomena among different phases such as occur in disperse flows, gas–liquid and liquid–liquid flows, flows in porous media, boiling, granular flows and others.
The journal publishes full papers, brief communications and conference announcements.
