This paper reviews passive heat transfer enhancement techniques for tubular heat exchangers, focusing on helical swirlers and twisted-tape inserts. These devices generate swirling flow and improve fluid mixing, resulting in significant increases in convective heat transfer. Reported studies show that productivity can be improved by up to 50–300%, while twisted tapes in laminar regimes may achieve up to a tenfold enhancement. Due to simple installation, low cost, and high thermal effectiveness, these technologies offer an efficient solution for upgrading existing heat exchangers and improving energy efficiency in industrial applications.
