基于重叠网格的真空管道高速列车运行条件对温度场影响分析
Overlapping Mesh-based Analysis of the Effect of Operating Conditions on the Temperature Field of High-speed Trains in Vacuum Tube
摘要
Abstract
In order to research the relationship between the temperature field inside the pipeline and the cross-sectional area of the pipeline,the vacuum degree and the running speed of the vacuum pipeline train during operation,the influence on the temperature field inside the pipeline and on the surface of the train were analyzed by using the simulation software Fluent and combining the overlapping mesh technology to simulate the different running speeds of the train,cross-sectional area of the pipeline and the vacuum de-gree.The results show that with the increase of pipe cross-sectional area and the decrease of running speed,it leads to the decrease of temperature on the surface of the train as well as inside the pipe.With the increase of vacuum degree inside the pipe,it has little effect on the temperature field inside the pipe,but it will make the temperature on the surface of the train show an upward trend.关键词
