摘要:
基于计算流体动力学软件ANSYS CFX,采用剪切应力传输(SST)k-ω湍流物理模型和非结构化网格,对山体环境下低矮民房中较为典型的二层双坡屋面房屋进行数值模拟.在山体环境影响下,分析房屋表面风压随山体高度变化、不同坐落位置和各风向角下的分布规律.结果表明,山体对房屋的影响,屋面的体型系数与平坦地区差异较明显,且与山体高度、山坡度和建筑的坐落位置有关.山体高度的变化对屋盖结构体型系数的影响较小,而房屋的坐落位置影响最为明显.
Abstract:
Based on computational fluid dynamics(CFD) software CFX,the shear stress transport(SST) k-ω turbulence physical model and unstructured grids,the numerical simulation is carried out for the typical low-rise two-story houses with double-sloping roof in the mountain environment.Under the influence of the mountain environment,the distribution of the roof pressure with different height of the hill,different houses locations and different wind direction is analyzed.The results show that the roof shape coefficients are obviously different to the one in the flat region,and are relevant to the height of the hill,slope degree,houses locations.The hill height influences little the roof shape coefficients,and the location of house influences most significantly the coefficient.
