摘要
对液氮辅助制冷冻干机的冷阱进行数值模拟,建立冻干机冷阱的三维几何模型和冷阱内流体流动控制方程及边界条件。采用Fluent模拟软件对冷阱室内温度场模拟分析,得到了冷阱室内温度场分布图,通过对冷阱内部温度场分析,为指导冷阱室内结构设计,提高冷阱捕水能力提供参考。
The cold-trap of freeze dryer cooled by liquid nitrogen was smulated and analyzed.The 3D geometric model of cold-trap and the control equation,edge conditions of fluid in the cold-trap were established.The fluent simulation software was used to simulate air temperature distribution inside the cold-trap.Through the analysis on the temperature field,it could be reference for restructuring the cold-trap design and enhancing the capacity of water-capture.
