In this work, a review on single-phase convective heat transfer enhancement based on multi-
longitudinal vortices is carried out. Theoretical investigations on convective heat transfer …

Inserts are used to enhance the heat transfer rates between the two fluids in heat exchanger
tubes. A variety of tube inserts such as twisted tape, wire coil, swirl flow generator have been …

In this study, a water-based graphene oxide nanofluid was utilized in a counter-current flow
double pipe heat exchanger (DPHE). The inner pipe carried the hot fluid (deionized water …

A novel curve tube design called Triple Tube Heat Exchanger was investigated to identify
the thermofluidic characteristics in the current paper. This research analysis comprises of …

A novel type of perforated vortex generators (PVGs) was developed to improve convection
heat transfer in the present work. The PVGs were used in the test section with four different …

In this paper, the experimental effect of the continuous and discontinuous twisted tapes
turbulator (perforated and non-perforated) on the inner side of the internal tube in the double …

Numerical analysis of the thermal and fluid behaviors of the tubes with multi-channel twisted
tapes has been investigated under constant wall temperature condition. The multi-channel …

The present work presents the thermo-hydraulic characteristics in the heat exchanger tube
inserted with multiple-twisted tapes (M-TT). Multiple-twisted tapes consisted of a larger …

This article reports a numerical study of enhancing heat transfer and thermal performance of
in a circular tube inserted by square cut twisted-tapes in comparison with that inserted by …

This paper reports a numerical study of the thermal performance enhancement of a circular
tube embedded with novel anchor-shaped vortex generators. The three-dimensional …
