Abstract

The simultaneous use of two passive methods (twisted tape and a nanofluid) in a heat transfer system will increase the average Nusselt number ( Nu ) of the system. However, the presence of inserts and nanoparticles inside the tube will create higher pressure drop ( ΔP ) in the system, which can eventually affect the overall enhancement ratio ( η ), especially at higher Reynolds numbers ( Re ). Several modifications of twisted tapes have been made to reduce ΔP , but most showed a decreasing trend of η as Re increased. The objective of this study is to design a new geometry of twisted tape that yields a larger value of Nu and a smaller value of ΔP, which can result in a larger value of η especially at higher Re . A simulation and experimental analysis are conducted in which Re ranges from 4000–16,000 with two types of nanofluids (SiC/Water and Al 2 O 3 /Water) at various values of the volume fraction, ( φ) (1–3%). ANSYS FLUENT software with the RNG k-? turbulent model is adopted for the simulation analysis. Three types of twisted tape are used in the analysis: classic twisted tape with a pitch ratio of 2 (TT PR2), constant-increasing-pitch-ratio twisted tape (TT IPR) and constant-decreasing-pitch-ratio twisted tape (TT DPR). The use of TT IPR generates a stronger swirling flow at the inlet of the tube and smaller ?P , especially near the outlet region. The highest value of η is obtained for 3% SiC/Water nanofluid that is flowing through a smooth circular tube with TT IPR inserts at Re of 10,000.
