摘　　要：研究双层幕墙在外界大气总风压及温差作用下引起热气流流动状态,简化计算模型,建立通道各截面气流的贝努里能量方程、质量连续方程及相关动量方程、温度场方程,并在一维流动下寻求方程组的解析解,同时设计有限分析计算程序和给出计算实例。This paper research the hot air flow status on the effect of the outside air pressure and the difference in temperature inside the double curtain wall.On the channel crosssections inside the double curtain wall,the simplify the calculation model are founded and 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 analytical solutions are calculated.The computer software is developed using this method.Finally,the example is introduced.
