城市风道对狭长地块单元入口风环境的影响研究

Impact of Urban Breezeways on the Wind Environment of Residential Building Entrances in Linear Area

为研究狭长地块两侧城市风道对地块中小区单元入口风环境特征的影响,以某严寒城市小区为研究对象,通过现场实测收集实际风环境数据,再以计算流体动力学(Computational Fluid Dynamics,CFD)为技术支持,使用fluent软件模拟单元入口风环境,借助实测数据验证模型。之后提取城市风道的影响因子为变量,分别进行单一变量和多变量风环境模拟,定量研究不同因子对入口风场特征的影响。最终以营造良好风环境为目的,提出相应优化策略,为住区规划设计提供相应参考。

This study evaluated the impact of urban breezeways on the wind environment of residential building entrances in linear areas.A cold urban district residential area was taken as the object to collect actual wind environment data through field measurement.Then,Fluent was used to simulate the wind environment of residential building entrance supported by Computational Fluid Dynamics(CFD),and the model was verified with actual measured data.The influence factors of urban breezeways were chosen as variables.The single-variable and multiple-variable wind environment simulations were carried out respectively to discuss the influence of different factors on the wind environment of residential building entrances quantitatively.Finally,optimization strategies were offered to create a better wind environment and provided a reference for residential planning design.
