Heat transfer devices have been used for conversion and recovery of heat in many industrial
and domestic applications. Over five decades, there has been concerted effort to develop …

The objective of this article is to study the work carried out in heat transfer augmentation
using active and passive techniques. A comprehensive summary of the work is highlighted …

Due to the rapid development in micro manufacturing and 3D printing technology, the
complex shape of microchannel heat sink (MCHS) can be realized, instead of just the …

Turbulent flow characteristics and heat transfer performances of twisted tri-lobed tube (TTT)
and twisted oval tube (TOT) with Reynolds number of 8000–21,000 are experimentally …

The purpose of this study was to experimentally investigate the heat transfer and pressure
drop characteristics in the transitional flow regime of twisted tape inserts in a circular tube …

A 3-D numerical investigation is performed to evaluate the effect of variable twist pitch on the
hydrothermal behavior and entropy generation features of non-Newtonian water-CMC/CuO …

Heat transfer enhancement of twisted oval tube is mainly concentrated in the high Reynolds
number region. In the present study, the low Reynolds k-ε model is employed to investigate …

Enhancing heat transfer performance has been the main interest in the thermal engineering
field. Various enhancement methods have been proposed, including twisted and Multilobe …

In order to further improve the heat transfer performance inside tubes, a three-start twisted
tube combined with oval dimples is proposed. The effects of dimple depths on the …

In this study, the multi-objective optimizations (MOO) are conducted on a wavy twisted tri-
lobed tube using computational fluid dynamics (CFD) and genetic algorithm optimizer. To …
