Summary

This article focuses on the entropy generation analysis in a circular duct with internal longitudinal fins of different shapes for laminar flow. Three different fin shapes were chosen for the analysis: thin, triangular and V-shaped. Calculations were performed for various dimensionless lengths and numbers of fins, dimensionless temperature difference and fin angle for triangular and V-shaped fins. It was found that the number of fins and dimensionless length of the fins for both thin fins and triangular fins, and the fin angle for triangular and V-shaped fins, have significant effects on both entropy generation and pumping power. Furthermore, both entropy generation and pumping power also are influenced by dimensionless temperature difference.
