Numerical magnetohydrodynamic simulations of expanding flux ropes: Influence of boundary driving
Physics of Plasmas, 2013The expansion dynamics of a magnetized, current-carrying plasma arch is studied by means of time-dependent ideal MHD simulations. Initial conditions model the setup used in recent laboratory experiments that in turn simulate coronal loops [J. Tenfelde et al., Phys. Plasmas 19, 072513 (2012); E. V. Stenson and P. M. Bellan, Plasma Phys.

Transverse dynamics of dispersive Alfvén waves. II. Driving of a reduced magnetohydrodynamic flow
Physics of Plasmas, 2002The nonlinear dynamics resulting from transverse and quasi-transverse instabilities of a finite-amplitude dispersive Alfvén wave propagating along an ambient magnetic field is studied by direct numerical simulations of the three-dimensional Hall-magnetohydrodynamic (Hall-MHD) equations.

The normalized performance indicated by the product of βNH89>2 was achieved by a combination of the lower hybrid current driving (LHCD) and the ion Berstein wave (IBW) heating in the HT-7 tokamak. More than 80% of the plasma current was sustained by the LHCD and the bootstrap current. Large edge pressure gradients were observed. The magnetohydrodynamic

The alumina concentration in the bath plays a fundamental role on cell operation. Local depletion may lead to an anode effect when using carbon anodes. A mathematical model describing the alumina convection-diffusion process in the bath coupled to the cell magneto-hydrodynamic (MHD) in the presence of small bubbles is presented.

Abstract The next generation fusion device listed on ENN’s fusion roadmap, named as (ENN He-Long) EHL-2, is under both physics and engineering designs. The instabilities of ideal magnetohydrodynamics (MHD) mode and neoclassical tearing mode (NTM) stabilized by electron cyclotron current drive (ECCD) for EHL-2’s two typical operation ...
