摘要: Abstract Second-law analysis on a flat plate-fin array under crossflow was conducted, from which the entropy generation rate evaluated. Increase in fluid velocity would enhance heat transfer (or equivalently, reduce irreversibility). Nevertheless, owing to simultaneous increase drag force exerting fin bodies, hydrodynamic irreversibility increases as well. An optimal Reynolds number thereby exists over wide operating conditions. Optimal design/operational conditions were searched for basis of minimization.
