On the Prediction of Ventilation Characteristics in case Diesel Trains Run in Double Track Subway Tunnels

복선전철 구간 내 디젤차량 운행시 환기특성 예측에 관하여

Pollutants emitted by Diesel trains seriously affected on the ventilation characteristics in the subway or railway tunnel network systems. Thus, numerical prediction results and analyses are required to engineers who should design ventilation facilities. So here, this paper presents some numerical results about the ventilation characteristics, such as pollutants distributions and a suitability of the ventilation facilities pre-designed in case that diesel trains use the same railway track with normal passenger trains
