Abstract: The entropy generation of a fully developed laminar flow in a hexagonal duct is investigated in this study. A constant heat flux condition was applied in this analysis. Two fluids, water and engine oil, were used to study the effect of fluid properties on the entropy generation. The fluid properties were evaluated using average temperature between inlet and outlet duct sections. The aspect ratio of the hexagonal duct was varied to show its effect on the entropy generation. Attention was also given to the supplied heat flux affecting the entropy generation. Finally, the entropy generation calculated from the hexagonal duct was compared with that from rectangular and circular ducts having the same hydraulic diameter and cross-sectional area.
