摘要
本文根据关于具有运动内核的环形槽道的平行科特(Couette)紊流理论,对列车通过圆形隧道的空气阻力计算提出了一个比较简单准确的数学模型,并且可以扩展到任意隧道截面形状、列车中心在隧道任意位置的情况。
Based upon the theroy of the plane turbulent Couette flow in an annular channel with a moving core. A simpler and more accurate model for calculating the air drag of a train passing through a circular tunnel in eocentric position is presented and it can be ex-tended to any shape of cross sections of tunnels and trains at any position in atunnel.
