3629 高速列車によって地下駅内で発生する圧力変動の数値シミュレーション(S49-1 トンネルの空気力学と換気(1),S49 トンネルの空気力学と換気)  [in Japanese] 3629 Numerical Simulation of Pressure Changes in Underground Station Caused by High-Speed Train  [in Japanese]

When a high-speed train runs through a tunnel equipped with stations, pressure changes and train draft are brought about at the stations. It is necessary, therefore, to predict the changes of pressure and wind velocity for high-speed railways. A computer simulation program of one-dimensional unsteady compressible flow has been developed for the prediction up to about 500km/h of the train speed. This paper presents the calculation method and results of verification by model experiment.
