Heat transfer characteristics in a condenser of closed two‐phase thermosyphon: Effect of entrainment on heat transfer deterioration

Heat Transfer—Asian Research, 2000
AbstractCondensation heat transfer in a closed two‐phase thermosyphon is experimentally examined using two different types of test section. Test Section 1 is a straight‐pipe‐type thermosyphon, whereas Test Section 2 has a large‐diameter evaporator compared with a condenser to minimize entrainment at the evaporator.

Condensation heat transfer deterioration on superhydrophobic surface with dense nanostructures

Journal of Physics: Conference Series, 2022
Abstract Superhydrophobic surface with dense nanostructures was fabricated on copper substrate by template-assisted electrochemical deposition. During deposition process, bubbles generated and stayed at some regions to prevent the fabrication of nanostructure, yielding heterogeneous surface.

The effect of hydrodynamic flow unsteadiness on heat transfer enhancement in a channel with square ribs

MATEC Web of Conferences, 2017
The heat transfer coefficient has been measured in the channel with square ribs for the case of periodic flow rate variation. New technique for heat transfer coefficient measurements has been applied in the study.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

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 ...

Improved prediction of shell side heat transfer in horizontal evaporative shell and tube heat exchangers

, 2008
This paper presents an improved prediction method for the heat transfer and pressure drop in the shell side of a horizontal shell and tube evaporator. The results from an experimental test program are used in which a wide range of evaporating two-phase ...

Organ‐specific redox imbalances in spinal muscular atrophy mice are partially rescued by SMN antisense oligonucleotides

FEBS Letters, EarlyView.
We identified a systemic, progressive loss of protein S‐glutathionylation—detected by nonreducing western blotting—alongside dysregulation of glutathione‐cycle enzymes in both neuronal and peripheral tissues of Taiwanese SMA mice. These alterations were partially rescued by SMN antisense oligonucleotide therapy, revealing persistent redox imbalance as ...
