摘要：

Indoor air stability was defined as a type of characterstic or capability of indoor air to inhibit transverse motion of air parcel or particle, and it is categorized into three patterns, such as unstable, neutral, and stable patterns. Computational fluid dynamics (CFD) method was adopted, and the results show that if indoor air is unstable, turbulence flow is intensified and the pollution diffusion is reinforced along transverse direction that is perpendicular to the main flow direction, while turbulence flow is restrained when indoor air is stable. The paper presents a foundation theory for optimal design of indoor air distribution or limited space air distribution under the condition of low energy consumption, to control the contaminants effectively.
