水体对建筑自然通风热湿影响研究

Numerical Simulation of the Impact of Water Body on Building Natural Ventilation

提出了一个简单模拟室外水体对室内自然通风影响的算法.在此基础上运用统计学的方法对CFD计算的结果进行了统计相关分析与回归和参数敏感性分析,得到了水体大小、离建筑物距离,来流温湿度、风速等主要因素对室内相对湿度等的影响规律和具体的关联式.结果表明:室外来流湿度对室内湿度影响最为显著.

This paper presented a simple CFD algorithm for the simulation of the impact of outdoor water body on the relative humidity in the buildings with natural ventilation.The simulation results agree well with the measured data.The correlation and regression were performed on the simulation results.The sensitivity analysis shows that the impact of outdoor humidity parameters variation on the indoor relative humidity is mostly significant.The correlation relationship and the regression formula were obtained among water body area,distance from buildings,outdoor temperature,humidity and velocity of inflow and indoor relative humidity.
