摘要
本文采用CFD数值模拟分析技术,建立校园风环境的物理模型,采用k-ε湍流模型,对某大学校区校园风环境进行模拟计算,获取校园内风速分布和压力分布。模拟结果表明,在夏季气象条件下建筑前后压差可以满足室内自然通风的要求,有效降低空调开启时间,达到建筑节能效果;冬季气象条件下基本满足室外风环境的指标要求,可以保证师生室外活动的安全性。
The CFD numerical simulation analysis technology was adopted to establish the physical model of Campus wind environment, adopting the turbulence model to simulate the campus wind environment of the university, getting the wind speed distribution and pressure distribution in campus. The simulation results show that the pressure difference before and after the buildings in the summer weather conditions can meet the requirements of indoor natural ventilation, which can reduce air conditioning open time effectively, achieving the effect of building energy efficiency; in the winter weather conditions, it can satisfy the demands of outdoor wind environment indicators basically, and guarantee the safety of outdoor activities between teachers and students.
