- •
A novel grooved tube is proposed for heat transfer enhancement.
- •
Flow structures in the proposed enhanced tube are presented and analyzed.
- •
Effect of parameters on the thermal-hydraulic performance is examined numerically.
- •
Entropy generation analyses have been performed to reveal the physical mechanism.
