Simulation research on the influence of air distribution on condensation law of wall humidity source space

以防护工程内部湿源的产湿特点为研究对象,建立"壁面散湿湿源模型",进行气流组织形式对室内温湿度和壁面结露分布规律影响的数值模拟研究。通过提出模型空间温湿度分布和壁面结露的三维非稳态数学模型,利用FLUENT对模型进行数值计算,分析研究不同气流组织形式下"壁面散湿湿源模型"的室内温湿度分布规律,并通过编制的壁面结露计算程序,对结露时间、结露面积、结露量以及结露速率进行分析,模拟不同气流组织形式对壁面结露动态发展过程的影响。

Based on the characteristics of internal protection engineering humidity source as the research object,setting up'wall moisture-dispersing humidity-source model',experimental research and numerical simulation research were conducted which explored the influence of air distribution on indoor temperature and humidity and wall condensation distribution.By putting forward a three-dimensional transient mathematical model and using the FLUENT software for numerical computation,the influence on the distribution of indoor temperature and humidity based on the'wall moisture-dispersing humidity-source model'were analyzed under different air distribution.By writing a computer program for the calculation of wall condensation,the condensation time,condensation mass,condensation area and condensation rate were analyzed,and the influences of air distribution on the dynamic development of wall condensation process were simulated.
