摘要
通过对高大空间双向对喷之横向隔断气流用ｋ－ε模型进行计算机仿真，分析了形成横向隔断气流（气膜或气幕）的影响因素并找到了临界（隔断状态）参数．该研究对指导高大空间分层空调模型试验及其空调系统节能与优化设计具有重要指导意义．
This paper researched horizontal partition air flow in large space building by numerical simulation method with k ε model.The horizontal partition air flow is formed by paralleling a few nozzles efflux of both sides of large space building.Important influence factors,such as locate and size of nozzle,parameters of air flow of efflux nozzles,are showed clearly.Critical parameters which determine horizontal partition air flow are also presented.The research is important to guide layering air conditioning model test,energy saving and optimization design of air conditioning system in large space building.
