Abstract Scope |
Material structures in metal additive manufacturing are formed through melting and solidification in laser scanning. The melt pool flow plays important role for the formation of the solidification structures. In this study, a phase-field lattice Boltzmann (PF-LB) model was developed to numerically reproduce the melt pool flow with high accuracy. In addition, since high-resolution is required for the high-accurate melt pool flow simulation, we implemented multiple GPU parallel computing to achieve large-scale simulations. Then, we validated the developed simulation method by comparing the results with experimental results, such as melt pool and keyhole shapes. |
