基于FLUENT 的体育馆火灾温度场模拟与应用 1 1 2 [楼书含 ，王方 ，杨鹏 ] [1 中南大学资源与安全工程学院，长沙410083； 2 武汉安世亚太分公司，武汉430071)] [ 摘 要 ] 进一步提高体育馆类大空间建筑的防火水平，有效减少火灾损失，针对大窄问建筑防火的特殊 性。采用 CFD 计算软件 FLUENT6.3 建立某体育馆火灾温度场模型，并比较馆内各种自然通 风状态下的温度场变化。模拟馆内东墙的通风设备完全开启、部分开启和馆内北墙的通风设备 完全开启这 3 种情况 F 的体育馆火灾温度场。结果表明，体育馆内自然通风设施的数量和所 处方位对温度场的变化有较大影响，这为体育馆设施的资金投入方向提供了参考。研究表明， FLUENT 软件能较好地模拟大空间火灾温度场。 [ 关键词 ] 火灾；温度场模拟；FLUENT；体育馆；有限体积法 Numerical simulation and application on the temperature field for large gymnasium based on FLUENT 1 1 2 [LOU Shu-han ，WANG Fang ，YANG Peng ] [1 School of Resources and Safety Engineering Central South University, Changsha, 410083, China; 2 PERA Global, Wuhan Branch, Wuhan 430071, China] [Abstract] This paper is aimed at offering a cost-effective way based on a field grid and finite volume method to take fire prevention measures for large space buildings. In proceeding with our research, first of all, we have developed a gymnasium-like building, then simulate and compare the variations of the temperature field in different ventilation conditions by CFD calculation software FLUENT 6.3. Simulate three conditions of fire temperature field: the whole ventilation system is supposed to be used for the east side of gymnasium, part of the ventilation for the eastern side, or the entire ventilation power is used for the northern side of gymnasium. All in all, it is of great significance to set the main parameters during the
