Implication

Numerical CFD study compares heat transfer enhancements from different fin geometries in industrial exchangers, indicating effective design options.

Key Points

  • This study aims to evaluate the impact of various fin geometries on the thermal-hydraulic performance of shell-and-tube heat exchangers.
  • Conducted a numerical simulation using CFD techniques on a shell-and-tube heat exchanger.
  • Compared three fin designs: external segmented fins, continuous rectangular wrap fins, and internal twisted-tape inserts.
  • Measured heat transfer and pressure drop across different fin geometries.
  • Type 1 segmented fins enhanced heat transfer by approximately 12% with moderate pressure drop.
  • Type 2 helical fins provided similar thermal enhancement due to consistent surface contact.
  • Twisted-tape inserts (Type 3) achieved a 19% increase in heat transfer but with a higher hydraulic penalty.
