This paper presents a comprehensive review on heat transfer augmentation and pressure
loss reduction of compact heat exchanger (CHXs) by using interrupted surfaces in the form …

Longitudinal vortices are more efficient for heat transfer enhancement than transverse
vortices. A survey is given on triangular and rectangular protrusions from a heat transfer …

Winglet pairs are promising longitudinal vortex generators which can be used to produce
streamwise vortices that do not decay until further downstream and consequently increase …

The combination of multi-louvered fins and delta-winglet vortex generators is a promising
strategy to enhance heat transfer in flat-tube compact heat exchangers. This paper focuses …

This paper deals with the parametric study of major factors influencing thermal and flow
behaviors for delta winglet vortex generator (DWVG) pairs in a circular tube. The …

A numerical study was performed to investigate the thermal performance characteristics of
an enhanced tube heat exchanger fitted with punched delta-winglet vortex generators …

Surrogate-based optimization is employed to maximize the thermo-hydraulic performance of
a solar air heater duct with non-periodic rows of rectangular winglet pairs mounted in the …

The present work aims to perform a parametric study of heat transfer enhancement and the
associated pressure loss applied to louvered fins with rectangular winglet vortex generators …

In order to improve the safety performance of supercritical heat exchanger, vertical tubes
with three kinds of longitudinal vortex generators (LVGs) are numerically investigated to …

The heat transfer performance of a flat plate behind a 10 mm high (h) and 20 mm long delta
winglet was studied at a distance up to 30h in a wind tunnel at a Reynolds number based on …
