Numerical Analysis of Aerodynamics of High-Speed Trains Running into Tunnels

  • 摘要: 为了寻求减小气动作用的方法,基于三维非稳态粘性流的雷诺平均Navier-Storkes方程及两方程紊流模型,采用包含移动网格技术的计算流体力学方法,对高速列车进入隧道的气动作用进行了动态数值模拟;计算了2种车型(ICE和新干线300系)、5种车速(200,250,300,350和400 km/h)和5种隧道断面尺寸的列车-隧道流场,获得了隧道内压力和列车气动阻力的变化趋势,并分析了列车速度、阻塞比、车头形状和线路状况等因素的影响.研究表明,列车速度和阻塞比对气动作用的影响具有一定规律.
