摘要
回顾和评价了已报道过的激光熔池质场的数值模拟,认为建立一个考虑自由表面、湍流、自由表面物化反应及固—液界面糊状凝固区的真三维传热、传质数学物理模型是未来激光熔池质场数值模拟发展的关键,并给出了自己的工作步骤。
The reported numerical simulation of the composition field in laser melted pool is reviewed and trend in future offered by author in the field is true 3-dimensional mathema-tical physics mass-transfer heat-transfer model including free boundary, turbulence, physicoche-mical reaction in the boundary and mush zone at the liquid-solid interface, and the procedure dia-gram is given.
