Effects of Swirl Intensity on Heat Transfer & Entropy Generation in Turbulent Decaying Swirl Flow
Highlights • Accurate numerical model of anisothermal turbulent swirl flow was built & validated. • The swirl number is directly and inversely proportional to Nusselt & Stanton numbers, respectively. • Numerical simulations revealed that a critical swirl number exists (Sn≈0.278). • A novel correlation for predicting entropy augmentation number in swirl flow is proposed. • The entropy field in the flow core was found to be dominated by viscous irreversibilities.
