摘　　要：研究双层幕墙在温差作用下引起热气流流动状态。针对双层幕墙通道,建立气流的N-S动量方程、连续性方程和温度场方程,将通道分成有限段单元,在一维流动下寻求方程组的解析解,通过单元间的速度、压力及温度连续条件化为数值解,开发有限分析计算软件,并给出计算实例。The liquid status on the effect of the temperature difference inside the double curtain wall is researched. On the channels inside the double curtain wall, the Navier_Stokes momentum equations and the consecutive equations and the temperature field equations are constituted. Using the theory of one_dimensional liquid flow, the channel is divided into a series of discretional units, and the local analytical solution of the equations is founded. With the confined conditions and the connected conditions on the speeds and pressures and temperatures in the units, the whole numerical solution is transferred. Finally,the computer software is developed,and the example is introduced.
