摘　　要：阐述了热通道幕墙内部通道气流流动的规律。采用一维流动计算模型,建立各有限段剖面气流的贝努里能量方程、质量连续性方程,运用有限分析法寻求数值解,并设计专用的计算程序。通过热通道幕墙的多种工程模型试验,观察进出风口流场结构,实测局部阻力损失系数。最后给出了计算实例。The air flow computation model of the hot channel wall expounded. In the flow of the one-dimensional, the momentum equations and the consecutive equations and the temperature field equations were constituted. Using the theory of finite analysis method, the local analytical solution of the equations was founded. The whole numerical solution was transferred, and the finite analysis computer software was designed. According to the experiment model of the hot channel wall, these structures of export and entrance for air flow were observed, and the partial resistance loss coefficients were measured. Tthe example was given, and the calculation result was compared with the experimental result.
