Large-scale parallel lattice Boltzmann–cellular automaton model of two-dimensional dendritic growth

Abstract
An extremely scalable lattice Boltzmann (LB)–cellular automaton (CA) model for simulations of two-dimensional (2D) dendritic solidification under forced convection is presented. The model incorporates effects of phase change, solute diffusion, melt convection, and heat transport. The LB model represents the diffusion, convection, and heat transfer phenomena. The dendrite growth is driven by a difference between actual and equilibrium liquid composition at the solid–liquid interface. The CA te...

摘要：本文提出了一种极为可扩展的格子玻尔兹曼-细胞自动机（LB-CA）模型，用于模拟在强制对流条件下的二维（2D）枝晶凝固过程。该模型综合考虑了相变、溶质扩散、熔体对流以及热传输等因素。格子玻尔兹曼模型用于表征扩散、对流和热传递现象。枝晶的生长由固态-液态界面处实际与平衡液态组成的差异所驱动。细胞自动机（CA）部分则负责...
