摘　　要：讨论了普通房间热气流分层现象 ,使用数值仿真方法来研究这一问题 .使用了CTFFP和PHONIX两个软件进行了仿真 ,并对结果进行了比较 ,发现两者都可以很好地预测气流流动 .文章还讨论了影响分层现象的几个因素 (入口高度、热射流角度和热流方向等 .)The authors discuss the phenomena of hot air jet in an ordinary air-conditioned room. Numerical simulation method is used to study the problem. Both CTFFP program and Phoenix program are used to take a comparison between their results. It is found that both of them can predict the flow field well. Several factors to influence the delaminating problem, such as the height of the inlet, the angle of the supplied air jet and heat flux direction are discussed in the paper.
