论文摘要
本文代表了基于多相视野（MPF）方法的金属泡沫中微观结构形成的模型。通过在此MPF框架内使用无凝聚边界条件，可以完全防止气泡的聚结，从而集中于封闭的多孔微观结构的形成。对这种非润湿标准的修改允许共聚的控制和开放结构的演变。该方法经过验证，并用于模拟两个维度和三个维度的泡沫结构形成。
This paper represents a model for microstructure formation in metallic foams based on the multi-phase-field (MPF) approach. By the use of a no-coalescence boundary condition within this MPF-framework, it is possible to completely prevent coalescence of bubbles and thus focus on the formation of a closed porous microstructure. A modification of this non-wetting criterion allows for the controlled initiation of coalescence and the evolution of open structures. The method is validated and used to simulate foam structure formation both in two and three dimensions.
