摘要

伴随着激波、膨胀波等波系的综合作用，真空管道高速列车诱发的气动热效应十分明显。初始环境直接关系到管内列车气动性能的好坏，研究环境初始温度对真空管道高速列车气动特性的影响对未来真空管道列车运输系统的研发具有重要意义。在建立含动边界的准二维非定常数值计算模型的基础上，通过分子动理论描述气流物性变化，利用SST

转捩模型预测层流-湍流的混合流动状态，结合动网格技术实现了管内列车的跨音速运动，研究了273.15 K、300 K、350 K、400 K的初始环境温度下列车的气动特性变化。结果表明，随着初始环境温度增大，整车阻力减小，尾流扰动区发展过程减缓而车前扰动区发展过程加快，整个流场扰动区长度变化不大；在不同初始环境温度下，尽管尾流伴随着涡流脱落，但其温度波动的主频很低，约为0.76 Hz，波动幅度不超过2 K。

Abstract

Along with the comprehensive effects of both shock waves and expansion waves

the aerodynamic thermal effect induced by the high-speed train in an evacuated tube is severe. As the initial environment can directly affect the aerodynamic performance of the train in the tube

it is of great significance to study the initial ambient temperature effect for the future development of high-speed train transportation in evacuated pipelines. Based on the establishment of a quasi two-dimensional unsteady numerical model with moving boundaries

the aerodynamic characteristics of the train at initial ambient temperat

ures of 273.15 K

300 K

350 K and 400 K are studied. The physical property change of air is worked out using the molecular kinetic theory

the mixed flow state of laminar/turbulent flow is predicted using the SST

transition model

and the transonic motion of the train in the tube is simulated using the moving mesh technique. The results show that with the increase of the initial ambient temperature

the drag of the whole train decreases

and the development of the wake disturbance region slows down

while that of the front disturbance region of the train speeds up. At different initial ambient temperatures

although the wake region is accompanied by vortex shedding

the dominant frequency of the temperature fluctuation is very low

around 0.76 Hz

and the amplitude of the temperature fluctuation is less than 2 K.
