Abstract
In this study, smoke movement in tunnel lire with natural ventilation shaft has been investigated with various size of lire source. Gasoline pool lire with different size of diameter - 73mm, 100mm, 125mm and 154mm - was used to describe lire source. Experimental data is obtained with 1/20 model tunnel test and its results are compared with numerical results. The computation were carried out using FDS 1.0 which is a field model of lire-driven flow. Temperature profiles between measured and predicted data are compared along ceiling and near the ventilation shaft. Both results are in good agreement with each other. In order to evaluating a safe egress time in tunnel lire. horizontal smoke front velocity was measured in model tunnel fire tests and those are compared with numerical results. According to the presence or absence of natural ventilation shaft, ventilation effect are estimated quantitatively. Finally, this paper shows that computational fluid dynamics(CFD) is applicable to predict tire-induced flow in tunnel.
