A data report of the impact of different terrain types on the performance of windcatchers.

The reported data in this article were obtained through a series of numerical CFD simulations that quantifies the natural ventilation performance of a two-sided windcatcher exposed to free wind flow which is affected by various types of ground surface features. The data production process includes the generation of the geometry of the building model and the windcatcher (modelled in Rhino), the construction of the computational domain and a high-quality grid (Hexpress), setting up the appropriate boundary conditions, and applying the numerical solution settings and performing the simulations (using ANSYS Fluent). The conducted simulations provided the flow field and temperature distribution inside the building that was located in the city of Nottingham, the UK with the reference wind speed of 3.1 m/s at the reference height of 10 m. The influence of four different terrains (open, rough, suburban and urban regions) on the wind free stream was considered. The represented numerical data encourages further numerical and experimental investigations toward the efficient aerodynamic design of the windcatchers.

本文报道的数据是通过一系列数值计算流体动力学（CFD）模拟获得，旨在量化两侧受自由风流影响的吸风器（其地面表面特征对风流产生影响）的自然通风性能。数据生成过程包括建筑模型和吸风器（在犀牛软件中进行建模）的几何形状生成，计算域及其高质量网格（Hexpress）的构建，适当的边界条件设置，以及数值求解设置和模拟执行（使用ANSYS Fluent）。所进行的模拟提供了位于英国诺丁汉市、参考风速为3.1米/秒、参考高度为10米的建筑内部流场和温度分布。考虑了四种不同地形（开阔地、粗糙地、郊区和城市区域）对自由风流的影响。所呈现的数值数据鼓励进一步开展针对吸风器高效气动设计的数值和实验研究。
