摘要:
采用有限容积法,根据不可压缩粘性流体的Navier-Stokes 方程和Spalart-Allmaras 模型,对CMS-04 中低速磁悬浮列车运行的外流场特性进行了计算分析,分别计算了不同速度下无横风和有横风条件下的气动阻力。根据数据拟合出无横风与有横风的空气阻力公式,详细分析了各公式之间的差异。研究表明,在横风条件下推导出的阻力公式能够较好地反映出阻力随风速、车速的变化,为中低速磁悬浮列车准确的牵引计算提供帮助。
Abstract:
Based on Navier-Strokes equation of the incompressible viscous fluid and Spalart-Allmaras turbulence model, external flow field characteristics of the CMS-04 low speed maglev train were investigated using the finite volume method. The aerodynamic drag with and without the horizontal wind were calculated at different speeds, the drag equations were deduced by the data and the differences were analyzed particularly. It reports that the air drag’s variations with the speed of the vehicle and the wind, can be provided for the calculation of the low-speed maglev vehicle traction.
