Entropy generation and optimal analysis for laminar forced convection in curved rectangular ducts : A numerical study
TL;DR: In this article, the authors analyzed the entropy generation induced by forced convection in a curved rectangular duct with external heating by numerical methods and found that the major source of entropy generation in the flow fields with larger Dean number and smaller wall heat flux comes from frictional irreversibility; whereas for the flow field with smaller Dean number, and larger wall heat flow, the entropy generator is dominated by heat transfer irreversible.
