  1. Computational fluid dynamics ( cfd ) techniques are used to study and understand fluid behavior in tunnels. by simulating complex specific operational cases, we can educe velocity or flux distribution in tunnel under different ventilation and resistance situation and determine the favorable operational procedures of the erlang mountain tunnel ventilation in a fire case. comparison has been made between a simulation and experiment for some cases in order to prove the cfd model is powerful, so that enables the study of cases for which experimental data is not available

    採用本文將隧道內的氣流看成是理想流體的一維恆定流動,通過對山特長公路隧道半橫向通風系統建立隧道內的空氣動力學模型,利用計算機進行數值分析與計算,得出發生火災時,不同通風阻力條件下隧道中的風速分佈及流量分佈,並通過實驗室隧道模型實驗進行驗證與修,依據研究結果給出了山半橫向通風隧道的火災控制方案,從而解決了山公路隧道通風對火災的控制問題,同時為半橫向通風公路隧道的火災通風提供科學的方法。
