摘要:
 随着航天、机械等领域的飞速发展，超大尺寸工件的深冷处理需求日益突出，为弥补超大型液氮深冷处理设备在设计计算方面的空白，基于流体仿真软件Fluent对超大型液氮深冷设备进行仿真设计与分析。将深冷设备箱体、风扇、工件等整体建模，采用离散相模型模拟液氮喷雾和汽化过程，通过组分输运模型模拟气体热交换过程，通过流固热耦合分析模拟气体与工件的对流传热过程。基于上述分析方法，对在研的大型深冷设备开展分析，结果表明：设备内流场和温度场分布合理，低温氮气能够稳定覆盖整个箱体，箱内环境温度均匀，工件温度下降速率稳定，箱体设计较为合理。本文提出的分析方法可为液氮深冷及其他相关领域设备的研发设计提供有效参考。
Abstract:
 With the rapid development of aerospace, machinery and other fields, the demand for cryogenic treatment of ultra large workpiece is increasingly prominent. In order to make up for the blank of design and calculation of ultra large liquid nitrogen cryogenic treatment equipment, this paper carries out simulation design and analysis of ultra large liquid nitrogen cryogenic equipment based on fluid simulation software FLUENT. Modeling the cryogenic equipment box, fan, workpiece and so on, discrete phase model is used to simulate liquid nitrogen spray and vaporization process. The gas exchange process is simulated by the component transport model, and the convection heat transfer process of gas and workpiece is simulated by the fluid solid heat coupling analysis. Based on the above analysis method, the large-scale cryogenic equipment under research is analyzed. The results show that the distribution of flow field and temperature field in the equipment is reasonable, the low temperature nitrogen can cover the whole box stably, the ambient temperature in the box is uniform, the temperature drop rate of workpiece is stable, and the box design is more reasonable. The analysis method proposed in this paper can provide an effective reference for the development and design of cryogenic equipment in liquid nitrogen and other related fields.
