Turbulence and heat transfer are two critical factors in the chain of world energy
consumption. Hence, development of more efficient energy transfer techniques in …

Supercritical and trans-critical carbon dioxide cycles are widely used for refrigerators, heat
pumps and power plants, of which the heat exchangers are key components. This article …

Microchannel heat sinks (MCHSs) are widely used in microelectronic systems and are one
of the most effective heat sinks in the 21st century. In this work, the fluid flow and heat …

Innovative designs of heat exchangers are crucial to increase the heat transfer effectiveness
for the purpose of compactness, energy savings, and emission reductions, among others. In …

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 …

In this study, a new type of insert, named center-tapered wavy-tape insert, which is designed
from bionics based on the movement of cuttlefish, is introduced. The thermo-hydraulic …

It is really important for a closed oscillating heat pipe (COHP) system to achieve a higher
heat dissipation capacity. In this work, a novel narrow-tube closed oscillating heat pipe …

With efficient heat dissipation capacity, the microchannel heat sink (MCHS) can be exploited
and applied in the development of new energy technologies. With 2.8 MHz high-frequency …

In this paper, a wavy-tape insert prototype for pipe heat transfer augmentation is reported.
The wavy-tape is fitted in the center of a straight pipe. The flow and heat transfer characters …

The internal flow in corrugated tubes of different helical pitch, covering from the laminar to
turbulent regime, was studied in order to characterize the three-dimensional flow and the …
