摘要
为探讨极小居住空间室内气流组织的特性,搭建了1∶1实体尺寸的建筑模型,采用CFD(computational fluid dynamics)模拟软件,通过实测的边界条件,应用RNG(re-normalization group)κ-ε高度紊流控制方程,分析了室内任意空间点气流的分布情况.结果表明,对于布局既定的极小居住空间,室内空气的流动明显受限于室内布局,且相互干扰;局部空间因家具的阻挡作用,空气能得到及时更换.通过模拟可预测极小居住空间的通风效果,对合理改善和全面提高极小空间室内通风质量,具有一定的指导意义.
To explore the characteristics of tiny living space indoor air distribution, a 1 : 1 building model is constructed and the mathematics simulation is clone to research the indoor airflow of the tiny building. Boundary conditions are obtained by environment parameter measurement, indoor airflow distribution data are solved by RNG κ-ε highly turbulence control equation. It shows that the room temperature of the tiny living room will return to the ambient temperature, and the ventilation effect can be evaluated visually by simulation results which have certain guiding significance to improve the indoor air quality of tiny living space reasonably and comprehensively.
