地下鉄駅構内の空気流動に関する実験的研究 : 第1報, 駅内部空気流と列車風緩和

Scale model experiments were made to investigate the steady and unsteady airflow characteristics in an underground railway station. The experimental apparatus consists of a scale model of a two-layer underground railway station and train wind generators that simulate the steady and unsteady airflow caused by trains. The steady and unsteady airflows were measured with hotwire anemometers at several points of the station for several cases. The unsteady airflow patterns were almost identical to the estimated airflow patterns obtained from steady values. The method of reducing the train wind effect in a station by means of tunnel ventilation dynamic control was considered and its effectiveness was confirmed through experimentation.
