철도차량 피난모델링을 위한 유동계수에 관한 분석

초록

In order to rise up the accuracy of evaluation of egress safety for train car and facilities, analysis of egress route, scenario and the prediction by variation of flow rate were conducted. According to analysis of egress scenario for train, the extra time should be added to the time from train to safety area when the distance between the train car floor level and the track level exists. In the result of hand calculation, the egress time was 123.1 s at flow rate 0.5, was 61.5 s at flow rate 1.0, and was 41 s at flow rate 0.5.
