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. |
