摘要

为了避免列车直接起动带来的非物理现象，通过自定义程序和重叠网格技术分别控制列车速度和运动，基于IDDES湍流模型研究高温超导磁浮列车在加速启动阶段和匀速阶段的管内波系形成过程和传播特性，揭示了不对称模型下的波系时空分布特征。结果表明：列车加速向前运动，车前会不断产生压缩波，这一系列压缩波形成一道正激波。在匀速运行阶段，车前空间流场呈现准一维分布特性。尾流区较为复杂，存在着激波、膨胀波、涡对以及它们间的相互作用等复杂流动现象。在考虑悬浮间隙下，尾流区域的波系分布呈现明显的上下不对称性。由于反向旋转涡对的存在，不同高度水平面的尾流流场结构差异较大。在匀速运行阶段，扰动区长度均随着运行时间线性增加。

Abstract

To avoid the non-physical phenomena caused by the train's direct start

the speed and motion of the train were controlled by a user-defined function and an overset mesh technique

respectively. Based on the IDDES turbulence model

the formation process and propagation characteristics of the wave system inside the tube of a high-temperature superconducting maglev train was studied under two operation phases

i.e. accelerating operation and uniform speed operation

revealing the spatial and temporal distribution characteristics of the wave system under the asymmetric model. The results show that

as the train accelerates forward

compression waves are continuously generated in front of the train

and eventually form a normal shock wave. During the uniform speed operation phase

the spatial flow field in front of the train presents the characteristic of a quasi one-dimensional distribution. The wake region is more complex

with the presence of complex flow phenomena such as shock waves

expansion waves

vortex pairs and their interactions. The wave system distribution in the wake region shows an asymmetry between the top and bottom when the suspension gap is considered. The wake flow structure varies considerably along the height due to the counter-rotating vortex pair. In the phase of uniform speed operation

there is a linear relationship between the length of the disturbed region and the running time.
