| 摘 要： | 以CFD软件PHEONICS为基础，采用SIMPLE算法求解N-S方程，对地下车库火灾中烟气的流动、传热与燃烧过程进行数值模拟，得到着火空间的浓度场、速度场及温度场分布等。通过对两种条件下(侧排系统、顶排系统)火灾烟气运动的数值模拟，得出相同条件下顶排系统的排烟性能明显优于侧排系统的结论。

| Abstract: | By the use of a CFD software--PHEONICS, this paper introduces SIMPLE arithmetic to solve N-S equation, simulates the smoke flow,heat-transfer and combustion process as fire in underground garage, and obtains the vectorgraph of smoke,velocity and temperature. It also simulates two conditions of smoke motion (side-extraction system and coping-extraction system) by numerical arithmetic and concludes that coping-extraction system is superior to side-extraction system in fire control. |
