摘要
城市的空间形态直接影响城市冠层内大气与下垫面之间的动量、能量和物质交换,是影响城市微气候形成和演变的关键因素之一。根据计算流体动力学(CFD)理论,模拟计算以行列式组团布局形式的住宅小区在不同阻塞比、建筑覆盖密度下的对流交换强度,对比小区不同空间形态对室外热环境的影响程度,改善小区通风能力,提高热舒适性。
Urban spatial form directly affects the momentum,energy and material exchange between the atmosphere and the underlying surface in the urban canopy,which is one of the key factors affecting the formation and evolution of urban microclimate.According to the theory of computational fluid dynamics(CFD),the convective exchange intensity of residential quarters in the form of determinant group layout under different blocking ratios and building coverage densities is simulated.The influence of different spatial forms of residential quarters on outdoor thermal environment is compared to improve the ventilation capacity and thermal comfort of residential quarters.
