基于CFD数值模拟的绿色建筑通风设计可行性研究

Analysis of CFD numerical simulation method in traditional typical ventilation design in modern green buildings

随着建筑能耗日益增多,而通风设计在建筑设计中占有重要地位,因此先进科学的通风设计成为建筑设计中重要的一环。比较了国内外建筑通风设计的研究现状,通过介绍CFD数值模拟方法,引入有限元、Navier-Stokes方程、k-ε方程湍流模型等,再结合传统通风设计,将人工通风与自然通风的优势相整合,得到最优的通风设计方案。探析现代绿色建筑通风的设计优化,探索CFD数值模拟技术在绿色建筑设计的应用。

Along with the increasing of the building energy consumption and the important position of the ventilation design in the field of architecture designing,the ventilation design of advanced science becomes very important in architectural design.This paper co MPares the research of building ventilation design at home and abroad,and introduce finite element,Navier-Stokes equations,k-ε turbulence model and so on through the introduction of CFD numerical simulation method.And the paper also combine the traditional ventilation design,integrating the advantages of artificial ventilation and natural ventilation,to obtain the optimal ventilation design.This paper analyzes the design optimization of modern green building ventilation,and explores the application of CFD numerical simulation technology in green building design.
