Lattice Boltzmann方法在枝晶生长模拟中的应用 朱鸣芳1,苏敏1,孙东科1 (1.东南大学材料科学与工程学院,江苏南京,211189) 摘要:将模拟流场和浓度场的Lattice Boltzmann方法(LBM)和一个模拟枝晶生长的改进cellular automaton(MCA)模型相耦合,模拟了合金凝固过程中单枝晶在纯扩散和存在对流两种条件下的生长行为.结果表明:在纯扩散条件下,枝晶呈现对称生长形貌;但存在对流时,枝晶的生长在上游方向得到促进,而在下游方向受到抑制,形成了非对称的枝晶生长形貌.模拟的纯扩散和对流枝晶形貌与前期的MCA-传输模型的模拟结果吻合较好. 关键词:模拟; Lattice Boltzmann方法; 枝晶生长; [全文内容正在添加中] ......
