| 摘 要： | 建立了双层壁中层空间的流体动力学和传热学二维稳态数学模型。将内、外层玻璃幕墙的传热模型、遮阳板的传热模型相耦合计算出双层壁的热力性能。给出了不同高度上的温度和速度分布数据。计算结果与相关文献中的实验数据较吻合。

| Abstract: | Established a two dimensional physical model to predict the thermal characteristics of the double skin fa ades.A control-volume finite-difference procedure was used to solve the coupled equations reflecting the heat transfer in out skin,inner skin,blind plate and air cavity.The temperature and velocity profiles at different heights are presented.It agrees well with the measuring datum gained in the double skin facades of City Gate.Therefore the feasibility and accuracy of the present model has been evidenced. |
