Magneto‐Thermal Assessment of Ferrofluid Flow in Corrugated Porous Domain With Rotating Cylinder for Nuclear Systems

open access: yesInternational Journal of Energy Research, Volume 2026, Issue 1, 2026.
This research presents a novel approach by combining magnetohydrodynamic (MHD) flow with ohmic heating to investigate the conjugate mixed convective transport of ferrofluid in a discretely heated, smooth/wavy‐walled, square‐shaped porous compartment featuring a clockwise spinning cylindrical body positioned at various locations.

Spheromak Experiment Using Separate Guns For Formation And Sustainment [PDF]

open access: yes, 1996
An experiment is described that incorporates the use of separate magnetized plasma guns for formation and sustainment of a spheromak. It is shown that energy coupling efficiency approaches unity if the gun and spheromak are of comparable size.

On the Behavior of Two C1 Finite Elements Versus Anisotropic Diffusion

open access: yesInternational Journal for Numerical Methods in Fluids, Volume 97, Issue 12, Page 1541-1557, December 2025.
Bi‐cubic Hemite‐Bézier and reduced cubic Hsieh‐Clough‐Tocher finite elements, of class C1, are compared for the solution of a highly anisotropic diffusion equation. They are tested numerically for various ratios of the diffusion coefficients on different meshes, even aligned with the anisotropy.

Excitation of Whistler‐Mode Waves by an Electron Temperature Anisotropy in a Laboratory Plasma

open access: yesGeophysical Research Letters, Volume 52, Issue 22, 28 November 2025.
Abstract Naturally occurring whistler‐mode waves in near‐Earth space play a crucial role in accelerating electrons to relativistic energies and scattering them in pitch angle, driving their precipitation into Earth's atmosphere. Here, we report on the results of a controlled laboratory experiment focusing on the excitation of whistler waves via ...
