Entropy Generation and Heat Transfer Performance in Microchannel Cooling. [PDF]
Entropy (Basel), 2019 Owing to its relatively high heat transfer performance and simple configurations, liquid cooling remains the preferred choice for electronic cooling and other applications. In this cooling approach, channel design plays an important role in dictating the cooling performance of the heat sink. Most cooling channel studies evaluate the performance in view

The Effect of Heat Transfer on Turbine Performance [PDF]
Mechanical Engineering, 2019 Abstract For over 50 years, high-pressure gas turbine blades have been cooled using air bled from the compressor. This cooling results in very high rates of heat transfer, both within the fluid and within the blade, shown in figure 1. The heat transfer often occurs across large temperature differences and is thus highly irreversible.

Heat transfer performance of nanofluids in heat exchanger: a review
Journal of Thermal Engineering, 2023 Energy is a key aspect of any country’s economic development. Improving heat transfer performance leads to saving energy. Nanotechnology has a key role to play in optimizing heat exchangers. Fluids containing nanosized particles are called nanofluids. Nanofluids have higher thermal conductivity than typical liquids. This paper outlines current research

Heat transfer performance of Pulsating Heat Pipe with Hydrofluoroolefin
Transactions of the JSME (in Japanese), 2020 Pulsating heat pipes (PHP) are increasingly attracting attention for their potential to downsize electronic devices to be designed. Unlike conventional heat pipes, PHP maintains high heat transfer performance despite having a smaller diameter, and have a smaller dependence on heating orientation.

Heat Transfer Performance of Microfin Tubes and -Three-Dimensional Heat Transfer Tubes
Chemical Engineering Transactions, 2022 Condensation heat transfer characteristics under different working conditions were studied to determine the heat transfer performance in horizontal, smooth and enhanced heat transfer tubes. Condensation heat transfer of these tubes was studied using R410A for a range of mass flow rates from 250 to 450 kg m-2 s-1 and a saturation temperature of 45 ...

TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series B, 1991 A new enhancing technique was developed for a natural convection adjacent to a vertical, heated plate. In order to enhance the heat transfer, V-shaped diverter plates of which the edges faced upstream, were attached onto the vertical plate in a staggered layout.

Heat Transfer Performance of a Novel Multi-Baffle-Type Heat Sink [PDF]
Entropy, 2018 A new type of multi-baffle-type heat sink is proposed in this paper. The heat-transfer coefficient and pressure drop penalty of the employed six heat sink models are numerically investigated under five different inlet velocities. It is shown that Model 6 (M6) has excellent heat transfer performance as its heat-transfer coefficient reaches a value of ...

Particle shape effect on heat transfer performance in an oscillating heat pipe [PDF]
Nanoscale Research Letters, 2011 AbstractThe effect of alumina nanoparticles on the heat transfer performance of an oscillating heat pipe (OHP) was investigated experimentally. A binary mixture of ethylene glycol (EG) and deionized water (50/50 by volume) was used as the base fluid for the OHP.

FEBS Letters, EarlyView.The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...
