摘要:
平均风速值体现了室内风场的整体通风水平.为明确高层住宅室内平均风速与影响因子(风向角度、楼层高度、进风向窗墙面积比、进出风口面积比、进深开间比和距地高度)的关联性,选取湘南地区高层住宅为研究对象,运用计算流体力学(CFD)的方法,采用RNG K-ε湍流模型,对夏季室内风场进行模拟,通过多组模型的对比,定量分析了住宅室内平均风速与相关影响因子的关联度.结果表明:(1)室内平均风速与窗墙比和离地高度呈正相关关系;(2)在住宅进出风口面积比和进深开间比为1.00的情况下,室内平均风速达到最大值;(3)室内平均风速与各影响因子的密切程度由大到小依次为:进出风口面积比﹥进风向窗墙面积比﹥距地高度﹥进深开间比﹥风向角度﹥楼层高度.多元逐步线性回归表明,进出风口面积比和距地高度是引发湘南地区高层住宅室内平均风速差异的主导因子.该研究可为湘南地区高层住宅室内风环境的评估与优化提供科学依据.
Abstract:
The average wind speed value reflects the overall ventilation level of the indoor wind field. In order to clarify the correlation between the indoor average wind speed of high-rise residential buildings and the impact factors(wind direction angle, floor height, air-to-window wall area ratio, air inlet-outlet area ratio, entrance-to-depth opening ratio, and height above ground), high-rise residences in southern Hunan were selected as the research object. The RNG K-ε turbulence model is used to simulate the indoor wind field in summer by the method of computational fluid dynamics( CFD ). Through the comparison of multiple sets of models, the correlation between the average indoor wind speed of residential buildings and the related influencing factors is quantitatively analyzed. The results show that(1)the indoor average wind speed is positively correlated with the window-to-wall ratio and the height above the ground;(2)the indoor average wind speed reaches the maximum value when the area ratio of the air inlet and outlet of the residence and the ratio of the depth to the opening are 1.00;(3)The degree of closeness between the indoor average wind speed and the various influencing factors is as follows: air inlet/outlet area ratio>air inlet window/wall area ratio>height from ground>opening depth ratio>wind direction angle>floor height. Multiple stepwise linear regression shows that the area ratio of the air inlet and outlet and the height above the ground are the leading factors causing the difference of indoor average wind speed in high-rise residential buildings in southern Hunan. This research can provide a scientific basis for the evaluation and optimization of indoor wind environment of high-rise residential buildings in southern Hunan.
