摘要
利用某地地下车库模型,根据地下车库室内环境的特殊性建立数学模型,介绍采用计算流体力学软件FLUENT对地下车库通风时的气流组织作数值模拟仿真计算与分析,提出采用合理设置送、排风口的位置的方法来改进气流组织、加速污染物(主要是CO)排放的方案,并对其CO浓度场作进一步的模拟计算,从而为地下车库空气环境的数值模拟研究找到了一种新方法。
Sets up a mathematical model of a underground garage, considering the particularity of the air environment of the garage. Simulates and analyzes the air distribution in this garage numerically by FLUENT. Based on the simulation results, proposes improved air flow patterns and accelerated discharging the pollution by in mounting the settings of the supply fans and exhaust fan reasonably. Also supplies a new method for the numerical simulation research of the air condition of the underground garage by further simulation of the CO concentration field.
