| 摘 要： | 利用热和流体流动控制方程,同时考虑了黏性耗散效应,以伴有温差的强迫对流空调房间为研究对象,分析讨论了不同通风方式在同一送风速度下熵产的分布情况。分析结果表明：熵产主要分布在送风口和回风口区域,最大熵产出现在送风口区域;模型1同侧上送下回通风方式的熵产的面积加权平均最小,模型3异侧下送上回通风方式的熵产的面积加权平均最大;无论哪种通风方式,在总熵产中,黏性熵产占绝对比重。

| Abstract: | Based on the forced convection heat transfer driven by temperature difference in an air-conditioned room, by using governing equations of heat and fluid flow and considering the effect of viscous dissipation, the entropy generation distribution in different ways of the ventilation at the same velocity was analyzed. The results show that entropy generation mainly occurs on the inlet and outlet field, the maximum of entropy generation occurs on the inlet field, the weighted average of entropy generation area ... |
