Study on the Power‐Frequency Arc Extinction Characteristics of Semi‐Closed Short‐Gap Device

High Voltage, EarlyView.
ABSTRACT Multi‐chamber arc‐extinguishing devices have a simple structure and excellent arc‐extinguishing performance; thus, they have attracted considerable attention as lightning protection devices. However, the structural parameters of different models of the aforementioned devices vary, leading to inconsistent protection levels; therefore, the arc ...

Thermal and Bioconvective Modeling and Analysis of Unsteady Cu‐Water Nanofluid Flow through Porous Media with Gyrotactic Microorganisms

Engineering Reports, Volume 8, Issue 9, September 2026.
The current study investigated unsteady boundary layer flow of a Cu/H2O$$ \mathrm{Cu}/{\mathrm{H}}_2\mathrm{O} $$ nanofluid over an expanding sheet embedded in a Darcy porous medium, containing gyrotactic microorganisms. The model includes heat source effects, unsteadiness, buoyancy, slip conditions, and nanoparticle radius.

Structured Energy Conversion in Kelvin‐Helmholtz Instability

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract We present quantitative investigations of the energy conversion pathways—electromagnetic ϵEM $\left({{\epsilon}}^{EM}\right)$, fluid flow ϵf $\left({{\epsilon}}^{f}\right)$, and particle thermal ϵth $\left({{\epsilon}}^{th}\right)$ energies—within the Kelvin‐Helmholtz instability (KHI) observed by the Magnetospheric Multiscale mission. We find

DENSITY-MAGNETIC FIELD CORRELATION IN MAGNETOHYDRODYNAMIC TURBULENCE DRIVEN BY DIFFERENT DRIVING SCHEMES WITH DIFFERENT CORRELATION TIMES

The Astrophysical Journal, 2016
ABSTRACT Turbulent motions naturally produce density and magnetic-field fluctuations. Correlation between the two fluctuations is important for interpretation of observations, such as observations of the rotation measure (RM). In this paper, we study the effect of driving schemes on the density-magnetic-field correlation.
