室外风环境是影响生物环境和人体舒适性的重要因素之一。中国矿业大学（北京）校园是本研究的案例研究。利用PHOENICS模拟软件对室外风环境进行了数值模拟研究。研究了冬季和夏季的行人水平风（PLW）环境。根据数值模拟结果，对校园室外风环境现状进行了总体评价和分区分析。根据风环境评价结果和存在的问题，从校园规划、单体建筑形式、绿化配置等方面提出了改善高校室外风环境的措施和策略。其主要目的是进一步改善北京高校的室外空间环境，为有效改善高校风环境质量提供总体指导。该策略可为同类型校园风环境的整治和改善提供参考。本研究也可为室外热环境/行人环境研究提供数据支持和参考意义。
The outdoor wind environment is one of the most important factors influencing the biological environment and human comfort. The campus of China University of Mining & Technology (Beijing) (CUMTB) is the case study for this research. PHOENICS simulation software was used to carry out a numerical simulation study of the outdoor wind environment. The pedestrian‐level wind (PLW) environments for both winter and summer were investigated. Based on the numerical simulation results, the overall evaluation and subregional analysis of the campus’ current outdoor wind environment were carried out. Then, according to the results and problems of wind environment assessment, improvement measures and strategies of outdoor wind environment in universities are proposed from the aspects of campus planning, single building form, and greening configuration. The main goal is to further improve the outdoor space and environment of universities in Beijing and provide general guidelines to improve the quality of the universities’ wind environment effectively. The strategies can provide a reference for the same type of campus on wind environment renovation and improvement. This study can also provide data support and reference significance for outdoor thermal environment/pedestrian environment research.
