天井几何形态对赣南传统民居风环境的影响研究——以姚衙前历史文化街区“彭氏宗祠”为例

Study on the Influence of Patio Geometry on the Wind Environment of Traditional Folk Houses in Southern Jiangxi:A Case of“Pengshi Ancestral Temple”in Yaoyaqian Historic and Cultural Block

本文以赣州市章贡区姚衙前历史文化街区内的“彭氏宗祠”为实例,对其进行实测和仿真模拟,以天井进深面宽比为主要控制影响因素,通过建立理想模型并结合CFD仿真软件,对彭氏宗祠的风环境进行模拟。对模拟数值进行比较分析后,得出天井进深面宽比为3:2的赣南传统民居风环境理想模型,以期为赣南传统民居的保护提供改造设计思路。

This chapter takes“Pengshi ancestral temple”in Yaoyaqian historical and cultural block,Zhanggong District,Ganzhou City as an example,measures and simulates it.Taking the depth to surface width ratio of the patio as the main control factor,the paper simulates the wind environment of Pengshi ancestral temple by establishing an ideal model and combining with CFD simulation software,and compares and analyzes the simulation values.The ideal wind environment model of Gannan traditional folk houses with a depth to surface width ratio of 3:2 is obtained,which provides transformation design ideas for the protection of Gannan traditional folk houses.
