| 摘 要： | 浅埋地下工程围护结构三维非稳态传热由于受到工程埋深、几何型式、室外气象参数、室内周期性变化空气以及围护结构热特性参数等的影响而显得尤为复杂。将室内空气对围护结构传热的影响综合考虑，基于FLUENT商业软件采用耦合传热计算方法对三维非稳态传热进行数值求解。通过这一方法可以得到围护结构全年动态传热量，并可反求室内空气与围护结构的对流换热系数。

| Abstract: | Three dimensional no-steady heat transfer of shallow-buried underground buildings is particularly complex because of the impact of the depth of building,geometric type,outdoor weather parameters and thermal property of soil envelopes,and the variation of room air situation.Considering the influence of indoor air variation on heat transfer,the whole-filed method of conjugate heat transfer is applied to simulate and solve numerically the unite region of soil and room air with FLUENT 6.1.Based on this,the whole-year dynamic heat transfer of underground building envelopes can be obtained,and the results can be further used to solve the local and transient convective heat transfer coefficient between the room air and soil wall. |
