隧道汽车火灾数值模拟边界条件设置研究
Boundary condition setting of tunnel fire simulation
摘要：
对隧道汽车火灾数值模拟计算时的基础设置、隧道模型网格划分、火源设置、防排烟参数及车行疏散模拟设置等进行了探讨分析，建议网格划分尽量采用结构化网格，火源设置可采用快速t2火进行分析，结合隧道内的行车类型确定火灾规模，结合隧道的通风方式选用防排烟参数。

Abstract：
Discusses and analyses common setting, grid generation of tunnel model, fire source setting, setting of smoke control parameter and car movement setting in tunnel car fire simulation. There are some suggestions to simulation, including structured grid, rapid fire t2 applied for fire heat release rate, fire scale due to car type in tunnel, and smoke control parameters related to ventilation method.
