同心情况下列车通过隧道的空气阻力计算

Calculating the Air Drag of a Train Passing Through a Circular Tunnel in Concentric Position

本文根据具有运动内核的环形槽道的平行科特(Couette)紊流理论,对列车位于中心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。

Based upon the theory 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 concentric position is presented.
