在前人实验数据误差分析的基础上,基于空间热及污染物分布相关理论,采用数值模拟方法,对不同浮射流强度下热及污染物分布过渡区进行研究。研究表明,浮射流强度较低(如373 K)时,污染物分布过渡区将增厚,部分污染物由于扩散作用将与热出现明显分离现象,扩散至建筑下部空间,影响工艺及人员健康。 Based on the previous experimental data error analysis, based on the theory of space heat and pollutant distribution, the numerical simulation method was used to study the heat and pollutant transition zone under different intensity of the floating jet. The results show that when the intensity of the floating jet is low (eg, 373 K), the transition zone of pollutant distribution will be thickened, and some pollutants will obviously separate from the heat due to diffusion, spreading to the lower space of the building, affecting the process and personnel health.
