CFD数字模拟在建筑环境分析中的应用

通过几个实际工程在设计阶段的风、热环境的数值模拟，说明了利用建筑行业专用CFD分析工具可以高效的帮助设计人员在设计初期阶段验证设计规划是否符合规范，并提供改进的参考数据；本文还重点说明了个别建筑专业CFD软件功能中多重网格技术的优异处。最后介绍了利用CFD分析工具可以方便地调用国际上通用的建筑业的各种评价指标对设计进行评价，提供了设计人员向客户介绍自己设计是否合乎标准的工具。

Application of CFD for Thermal Fluid Simulation of Building Environment

This paper gives architectural design personnel the guideline in the design phase of the buildings through analyzing two case studies, one is fluid simulation for buildings in a city, the other is thermal fluid simulation for buildings in a residential area. These simulation data are helpful to the actual building layout, green building and choosing building ma- terials. This paper introduces the CFD simulation application in domestic and international advanced design. Especially, this paper introduces the professional building analysis module and the corresponding feature in the relevant software. These modules and features can help designers to finish building environment CFD simulation more conveniently and rapidly. So designers can finish more building CFD simulation in a short-term, and st the same tittle, designers can improve the build- ing design These advanced technology includes：Solar radiation used for steady-state analysis; the application of multiple grid technology for complicated buildings ;. The commonly used evaluation indexes for foreign building CFD simulation anal- ysis are introduced in this paper, for example： MRT, PMV, SET, Index for Age/Life Expectancy of Air, Inlet/outlet Contribution Rate, Ventilation efficiency and so on.
