TR型磁浮列车气动力特性数值计算研究

Research on Numerical Calculation for Aerodynamic Characteristics of the TR Maglev Train

根据可压缩粘性流体的N S方程和k ε双方程湍流模型,采用有限容积法对TR磁浮列车的气动力特性进行了数值计算研究,得到了以不同速度运行的磁浮列车的气动阻力、升力及横向气动力的大小,为高速磁浮列车的安全运行控制提供了气动力数据。

Based on the N-S equation of the compressible viscous fluid and k-ε turbulence model, aerodynamic characteristics of the TR train are investigated using the finite volume method. The aerodynamic drag, lift and side forces are calculated at different speeds. Results of this paper provide important aerodynamic data for safety running control of the maglev train.
