摘要:
针对高架仓库中易燃物资的着火特性,建立几何模型并应用涡团耗散模型对机械排烟条件下火灾烟气的速度、温度及燃烧反应物质的分布特性进行模拟.结果表明:冷热气体的流动使仓库中心形成低速回流区,燃料储存罐体周围烟气流速较低,冷空气入口和烟气排出口速度较高; 系统温度受进口风速、烟气流动和化学反应的影响呈现高度不均匀性,低温区主要在水平地面附近,高温主要在中心和排风扇出口的区域; 燃烧反应物主要分布在储存罐体的周围,系统中心处生成物浓度分布较高,不利于火情扑救.
Abstract:
Aiming at the inflaming property of flammable materials in a high rack warehouse,a geometrical model was established.ED(Eddy Dissipation Model)mode is used to make simulation on the speed and temperature of fire smoke under mechanical ventilation,and on distribution character of combustion reaction.The results show that the behaviors about the cool and hot fluid make a Low speed reflux zone in the center of the warehouse.The smoke is low in flow rate around the fuel storage tanks,and is high in flow rate in the inlets of cold air and the exhausted gas outlet of the system.The temperature distribution is influenced by cool air,behavior of the flue gas and chemical reactions.The lower value is near the floor,while the higher zones are near the center of the warehouse and the outlet of the extractor fans.Combustion reactants are mainly distributed near the storage tanks,and the higher concentrations of the products including CO2 and H2O in the center lead to a disadvantage over the fire fighting.
