水环境对建筑空间环境影响的数字化关键技术研究

Living on water, a residential architecture culture，which has developed from originally meeting basic living requirements and dealing with traffic problems to today's enjoying these beautiful visual impressions and enhancing living quality. However，water is not just limited to bring visual impressions, it is closely related to the building space where we live. In this project, to analyze the impacts of water on wind environment and building space environment, digital technology is comprehensively applied and CFD numerical simulation is made full use. At present, studies on the influence of water on land surface wind environment are few both in China and abroad, so numerical water surface evaporation model is introduced creatively. And then the evaporation model is further expanded and established on the basis of Dalton numerical model and Min Qian model and is modified repeatedly by wind tunnel experimental method and actual measurement method. Finally, the numerical simulation method could be adopted to research the impacts of several water forms on building space in building energy conservation and livability. The results of this project will play a positive role in making design schemes for architectural planning and building energy saving, thus temperature and humidity of architectural environment could be efficiently regulated and heat island effect could be reduced by using water environment models and designing reasonable water distribution and the architectural layout, therefore the thermal comfort of architectural space environment would be improved to provide scientific basis and evaluation standard for optimizing water environment design of architectural space.

临水而居已经从最原始的解决生活、交通问题发展到现如今的享受美好视觉观感，提高生活品质方面，但水不仅仅局限于带来视觉观感，它与人们所生活的建筑空间息息相关。本项目综合应用数字化技术，充分利用CFD数值模拟软件来分析研究水体对风环境的影响，进而对建筑空间环境的影响。国内外目前关于水体对陆面风环境影响的研究甚少，本项目创造性的引入了水体蒸发数值模型模拟，在道尔顿数值模型、闵骞模型的基础扩充建立水体蒸发数值模型，并利用风洞实验法和实测法进行反复修正，最终能利用该数值模拟方法研究不同形态水体对建筑空间在建筑节能与宜居性方面的影响。本项目的研究成果将对建筑规划和建筑节能的设计方案起到积极的作用，利用水环境模型，合理地设计水体分布和建筑布局，可以有效地调节建筑环境的温度和湿度，减缓城市的热岛效应，提高建筑空间环境的热舒适性，为优化建筑空间的水环境设计提供科学依据和评判标准。
