摘要
由室内污染源、热源形成的浮力羽流广泛存在,其对室内环境及其空气品质的作用影响引起了人们越来越多的关注。室内污染源、热源多以多点多处的形式存在,Pera&Gebhart通过定义两羽流浮力通量比,得到两股等羽流和不等羽流的混合高度模型以及混合之后形成单一羽流的运动控制方程,本文对多股羽流混合运动机理模型进行综述,并加以实例计算分析上述机理研究成果。
Because of indoor sources, the heat source to form a buoyant plume widespread, the role of the indoor environment and air quality impact caused the people more and more attention. Indoor sources of pollution, heat and more exist in the form of multi-point locations. Pera ＆ Gebhart denoted the ratio of the buoyancy fluxes of two plumes, and got the merged height model and coalesced axisymmetric turbulent plume motion control equation of two equal and two unequal plumes, I reviewed the plume mixing multi-strand movement mechanism model, and instanced calculation analysis of research results of the above-mentioned mechanism.
