双层集装箱列车与客运列车交会空气压力波数值模拟计算

Numerical simulation on the pressure pulse from double-stack freight train passing passenger train

采用求解三维不可压非定常N-S方程的方法,对DX1型双层集装箱与25Z客车交会时的周围流场进行数值模拟,求解出交会过程中所产生的交会压力波,为集装箱列车交会稳定性的研究提供依据。

In this article, a three-dimensional flow fluid induced by type DX1 double-stack freight train passing by passenger train is studied based on the numerical simulation of the three-dimensional incompressible N-S equations. The air pressure pulse during the crossing is computed. The results supply the basis for the study on freight train crossing stability.
