Research Abstract

The subway system vecoems of improtance as a rapid transportation system in urban ares. In propostion to the incresing of subway systemems, which are consisted of the tunnel and the station precincts, the tunnel are mode digging depp, because the shalloe region ogf the undergouund have already been occupied by the existing subway system and bulifigs. And subway systems are made sticking the tunnerl fast to the train for economical reason. Therefor the blockage ratio which is the ratio of a cress section of he train to the tunnel becomes of large. Since the system of bouble tunnel with single track are adopted rather then the system of single tunnel with double track in the latest subway constructions, the subway system are on the rise in it's complexity. Therefor, the engineering concerning with safety seandard of efficlenty of ventilation and etc. are requested the more detailed developments in the subway system.
In the subway system, the unsteady airflow causing by the reansient behavior of the train. In order to investigate the engineering concering with safety standard or efficiency of ventiliation of subway systems, we studied the aerodynamical behaviour of this unsteray airflow in the tunnal with a moving train.
The experiments in which the model train runs in a manner of the actual subway train are made in our research project.
The theoretical developments are down to maek analysis the date from this model experiments. We represinted the theor which based on the ideal gas approximations.
By making use of this theor, we can forecast the Aerodynamical phenomena of actual subway system.
