摘要
以夏季华南地区湿热气候为背景,采用计算流体力学方法模拟了水体对居住小区局地气候调节作用,根据模拟结果研究水体对居住小区风场、湿度场和温度场的影响。结果显示:水体在白天增温阶段有降温作用,傍晚降温阶段起保温作用,并有增湿和调节风速的作用,7.5%面积占有率的水体能很好改善20 m区域内气候。
Using computational fluid dynamics method, a numerical simulation was conducted for local climate influenced by water pond within residential districts under the typical summer warmer and humid meteorology in southern China. The summary results demonstrate that the water pond plays a role in cooling in the daytime heating stage and heat preservation in the evening cooling stage. In addition, the exist of water pond can increase humidity and adjust the wind speed around it. The area occupancy of 7.5% of the water pond can well improve microclimate around water pond up to 20 m.
