환기시스템 적용 도로터널의 국소환기 특성 시뮬레이션 및 해석

In this study, a design program for ventilation requirements of a longitudinal road tunnel were developed and investigated. The control volume method was applied to calculate the local air velocity and the local concentration distribution of pollutants, CO, NOx, soot along the tunnel for various tunnel ventilation system. This program was validated by comparing with the practical design data for the road tunnel ventilation system. The calculation results were in good agreement with the practical design data.
