Direct numerical simulation of heat transfer from the stagnation region of a heated cylinder affected by an impinging wake [PDF]
, 2011 Copyright © 2011 Cambridge University Press.The effect of an incoming wake on the flow around and heat transfer from the stagnation region of a circular cylinder was studied using direct numerical simulations (DNSs).

Heat Transfer in Drop-Laden Turbulence
Journal of Fluid MechanicsHeat transfer by large deformable drops in a turbulent flow is a complex and rich-in-physics system, in which drop deformation, breakage and coalescence influence the transport of heat. We study this problem by coupling direct numerical simulation (DNS) of turbulence with a phase-field method for the interface description.

DNS Study of Effects of Suddenly-Vanishing Wall Heating in Turbulent Boundary Layer
Journal of Thermal Science and Technology, 2012 The objective of this study is to investigate a thermal field in the turbulent boundary layer by means of direct numerical simulation (DNS), in which the wall heating has suddenly vanished in the downstream region, i.e., the wall is heated by a constant ...

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 ...

Numerical Analysis of Turbulent Mixed Convection in Vertical Annular Channel
Yuanzineng kexue jishu, 2023 Reactor cavity cooling system (RCCS) is a competitive residual heat removal scheme for small modular reactors. In this paper, the RCCS has been simplified to a scenario that ascending air flow is got heated in vertical annular channels and driven by ...

Electromagnetic enhancement of turbulent heat transfer
Physical Review E, 2008 We performed large eddy simulations (LES) of the turbulent natural convection of an electrically conductive fluid (water with 7% Na2SO4 electrolyte solution) in a moderate (4:4:1) aspect ratio enclosure heated from below and cooled from above and subjected to external nonuniformly distributed electromagnetic fields.

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 ...
