摘要
对管内、管外流动传热进行了熵产分析,在此基础上讨论了管内、管外传热强化分别相对于未强化的光管的热力学性能比较,分析了由传热不可逆和流动摩擦不可逆组成的总熵产的变化及两种不可逆在总熵产中的分配情况。
Entropy analysis is carried out for enhancement of
internal and external duct in this paper. Thermodynamic performance is compared before and after
enhancement. The overall entropy generation including heat transfer and flow friction
inreversibility as well as the contribution of these two kinds are analysized. Numerical examples
of two kinds of enhancement are presented. The results are of importance to instruct the study as
well as application of enhancement.
