基于CFD技术的群体建筑风环境分析

Wind Environment Analysis of Group Buildings Based on CFD Technology

随着高层群体建筑的不断建设,其周围往往会形成不利于行人的复杂风环境,因此在对建筑进行规划与设计的过程中,需要先对其风环境进行有效测算。基于此,文章对群体建筑风环境的研究现状展开讨论,并对计算模型的构建加以分析,进而通过N-S方程以及RNG k-ε湍流模型对单体建筑与群体建筑的风环境进行数值模拟。对于测算数值展开进一步分析,提出相应的改进策略。

With the continuous construction of high-rise group buildings, a complex wind environment unfavorable to pedestrians is often formed around them. Therefore, in the process of building planning and design of buildings, it is necessary to effectively calculate the wind environment first. Based on this, this paper discusses the research status of group building wind environment,analyzes the construction of calculation model, and then, the paper numerically simulates the wind environment of single building and group building through N-S equation and RNG K-ε turbulence model. The calculated values are further analyzed and the corresponding improvement strategies are put forward.
