Implication

Comparative trial shows enhanced heat transfer in tubes with grooved twisted tapes, indicating superior designs.

Key Points

  • This study aims to evaluate heat transfer enhancements using grooved twisted tapes and identify optimal designs.
  • Conducted CFD analysis on heat transfer in tubes with circular, rectangular, and triangular grooved twisted tapes.
  • Compared grooved configurations against smooth and conventional twisted tapes at Reynolds numbers from 5000 to 20,000.
  • Analyzed velocity fields, streamline patterns, and thermodynamic characteristics.
  • Grooved twisted tapes increase Nusselt number by 1.472–1.98 times compared to smooth tubes.
  • CGTT configuration shows the lowest entropy generation with Bejan number of 0.999841 at Re = 5000.
  • CGTT achieves the highest thermal performance factor of 1.294 at Re = 5000, outperforming other designs.
