摘要: 在热源参数一定而分别改变进风口面积、进风口离地高度、矩形天窗喉部开口面积及排风口面积等建筑结构参数的情况下，对工业厂房自然通风的流场和温度场进行了数值模拟，得到了不同计算工况下的通风量、排风温度、工作区的平均温度、热量分布系数及其变化规律，分析了工业厂房的建筑结构对自然通风的影响。 关键词: 工业厂房 建筑结构 自然通风 热量分布系数 Numerical simulation of effect of building structure on natural ventilation in industrial workshops with heat sources By Wan Xin★ and Su Yaxin Abstract For the constant heat source intensity, numerically simulates the flow and temperature fields in the workshop on conditions of different air inlet areas, distances between inlet height and floor, areas of rectangular skylight and air outlet areas. Obtains the ventilation rate, outlet air temperature and the mean air temperature in working area and the heat distribution coefficient in different calculation conditions and their varying patterns. Analyses the effect of building structure of industrial workshops on natural ventilation. Keywords industrial workshop, building structure, natural ventilation, heat distribution coefficient
