Abstract
Second-law analysis on the herringbone wavy plate fin-andtube heat exchanger was conducted on the basis of correlations of Nusselt number and friction factor proposed by Kim et al. (1997), from which the entropy generation rate was evaluated. Optimum Reynolds number and minimum entropy generation rate were found over different operating conditions. At a fixed heat duty, the in-line layout with a large tube spacing along streamwise direction was recommended. Furthermore, within the valid range of Kim et al. 's correlation, effects of the fin spacing and the tube spacing along spanwise direction on the second-law performance are insignificant. ? 1998 by ASME.
