Implication

Randomized trial evaluates heat transfer in shell and tube heat exchangers using fin parameters, highlighting optimal designs.

Key Points

  • The study aims to evaluate how different fin parameters affect heat transfer performance in shell and tube heat exchangers.
  • Conducted simulations using the EWT Realizable k-ε turbulence model under steady-state conditions.
  • Analyzed parameters like fin height and spacing for their impact on heat transfer, Nusselt number, and pressure drop.
  • Utilized response surface methodology to identify optimal fin configurations.
  • Finned tubes increased the Nusselt number by up to 28.6% compared to smooth tubes (Nu).
  • Total heat transfer rate rose by 13.55%, while pressure drop (ΔP) increased by 9.81% to 16.5%.
  • Optimal fin height of 2-3 mm and spacing of 10-15 mm was determined for best performance.
