Abstract
This work had theoretically investigated the fin performance and entropy generation rate of a fractal-like fin under a crossflow. Both contracting and expanding fins were considered. Performacne analysis had recommended a fin with one or two generations of branching and an as high as possible Reynolds number. The second-law analysis, on the other hand, suggested an optimal Reynolds number for all contracting fin, and for expanding fin with a finite generations of subfins. An estimate for the optimal Reynolds number was proposed and compared with the numerical results.
