steel research international, Volume 93, Issue 12, December 2022., 2022 A numerical verification of the role of mold electromagnetic stirring (M‐EMS) speeds up the superheat dissipation in the mold region, leaving the liquid core out of the mold region largely undercooled. 1) Simulation results of the surface temperature and M‐EMS‐induced flow pattern of billet continuous casting; and 2) comparison of the inner temperature

IET Electrical Systems in Transportation, Volume 12, Issue 4, Page 238-250, December 2022., 2022 Abstract With the increase of train speed in electrified railways, the increasingly violent interaction of pantograph–catenary (PC) makes the PC detachment arc an extrusive phenomenon, especially in the double‐pantograph–catenary (DPC) system. Despite a large number of research studies have focussed on the PC arc in a single pantograph system, the ...

Experimental investigation of magnetic islands growth in tokamak plasmas by applying emissive biased limiter and resonant helical field [PDF]
Iranian Journal of Physics Research, 2020 At the present time, Magnetic Confinement Fusion (MCF) is considered as a way to produce energy. In this work, one of the Magnetohydrodynamic (MHD) limitations has been discussed.

Space Weather, 2021 Previously, Tsurutani and Lakhina (2014, https://doi.org/10.1002/2013GL058825) created estimates for a “perfect” interplanetary coronal mass ejection and performed simple calculations for the response of geospace, including dB/dt.

High-order coupling of shear and sonic continua in JET plasmas
Nuclear Fusion, 2023 A recent model coupling the shear-Alfvén and acoustic continua, which depends strongly on the equilibrium shaping and on elongation in particular, is employed to explain the properties of Alfvénic activity observed on JET plasmas below but close to the ...

The Astrophysical Journal, 2023 The angular momentum of gas feeding a black hole (BH) may be misaligned with respect to the BH spin, resulting in a tilted accretion disk. Rotation of the BH drags the surrounding spacetime, manifesting as Lense–Thirring torques that lead to disk ...

IET Generation, Transmission & Distribution, 2023 Following the design demands of the protective switch used in ±800 kV hybrid UHVDC system, a plasma‐triggered‐based protective gas switch (PTGS) is developed by performing the comparative study of its dynamic performance by considering the arc dynamic ...

Local Radiative Hydrodynamic and Magnetohydrodynamic Instabilities in Optically Thick Media [PDF]
Astrophys.J. 596 (2003) 509-537, 2003 We examine the local conditions for radiative damping and driving of short wavelength, propagating hydrodynamic and magnetohydrodynamic (MHD) waves in static, optically thick, stratified equilibria. We show that so-called strange modes in stellar oscillation theory and magnetic photon bubbles are intimately related and are both fundamentally driven by ...

Toward 3D MHD modeling of neoclassical tearing mode suppression by ECCD
EPJ Web of Conferences, 2012 We propose a framework to extend the magnetohydrodynamic (MHD) equations to include electron cyclotron current drive (ECCD) and discuss previous models proposed by Giruzzi et al. [2] and by Hegna and Callen [3].
