トンネル内火災時に発生する熱気流のに関する数値シミュレーション

抄録

In case of an emergency fire in tunnel, proper operation of the ventilation system which controls the thermal fume and smoke induced by fire accident to remain an available evacuation and extinction envjronment is very immportant. In this paper, a three-dimensional numerical simulator using LES turbulence model is developed and the themal behaviors of an emergency fire in tunnels is investigated. Furthermore, several modelling parameters applied in this simulator are examined. Comparison of the numerical simulation results and the fire test results obtained from a real vehicle tunnel shows that the present simulator has a good reliability on the numerical analysis of emergency fire in vehicle tullnels.
