摘　　要：利用FLUENT软件对加气混凝土外墙与钢筋混凝土楼板构成的T型热桥进行了数值模拟计算,通过二维稳态、二维非稳态两种模型计算结果对比,得出以冬季采暖期的室外计算温度作为稳态计算的室外边界条件是合理的。Used the FLUENT software, numerical simulation are carried on T type thermal bridge which is constitute by external wall and reinforced concrete ceiling. By simulation result contrast of two-dimensional steady models and unsteady models, it is reasonable that design temperature of winner heating is considered as outdoor boundary condition.
