An extended hybrid magnetohydrodynamics gyrokinetic model for numerical simulation of shear Alfv\'en waves in burning plasmas

open access: yes, 2010
Adopting the theoretical framework for the generalized fishbonelike dispersion relation, an extended hybrid magnetohydrodynamics gyrokinetic simulation model has been derived analytically by taking into account both thermal ion compressibility and ...

The Exact Solution of the Riemann Problem in Relativistic MHD [PDF]

open access: yes, 2006
We discuss the procedure for the exact solution of the Riemann problem in special relativistic magnetohydrodynamics (MHD). We consider both initial states leading to a set of only three waves analogous to the ones in relativistic hydrodynamics, as well ...

A Compact, High‐Performance, and Deformation‐Resilient Trielectrode Electrostatic Soft Pump for Soft Robotics

open access: yesAdvanced Intelligent Systems, Volume 7, Issue 3, March 2025.
Existing soft pumps often require tradeoffs between performance and compatibility with soft robotic systems. The proposed trielectrode electrostatic soft pump addresses these limitations through an innovative driving mechanism. Its design, which includes a trielectrode configuration and the use of compliant materials, improves operational efficiency ...

Magnetohydrodynamics of HEMP [PDF]

open access: yes, 1973
Using the continuum mechanics approach, details are presented for solving the equations of magnetohydrodynamics in two space dimensions and time. The problem considers cylindrical symmetry, in that only the H θ component of a magnetic field is present.

Stability of an Axisymmetric Liquid Metal Flow Driven by a Multi-Pole Rotating Magnetic Field

open access: yesFluids, 2019
The stability of an electrically conducting fluid flow in a cylinder driven by a multi-pole rotating magnetic field is numerically studied. A time-averaged Lorentz force term including the electric potential is derived on the condition that the skin ...

On the convexity of Relativistic Ideal Magnetohydrodynamics [PDF]

open access: yes, 2015
We analyze the influence of the magnetic field in the convexity properties of the relativistic magnetohydrodynamics system of equations. To this purpose we use the approach of Lax, based on the analysis of the linearly degenerate/genuinely non-linear ...

A mixed DG method and an HDG method for incompressible magnetohydrodynamics [PDF]

open access: yesIMA Journal of Numerical Analysis, 2017
In this paper we propose and analyze a mixed discontinuous Galerkin (DG) method and an hybridizable DG (HDG) method for the stationary magnetohydrodynamics (MHD) equations with two types of boundary (or constraint) conditions.

Optimization of Thermally Radiative and Mass Wavy Flow Analysis Affected by Induced Magnetic Field and Joule Heating

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT The role of magnetic induction is declared fundamental in many technological systems, including electric generators, inductors, transformers, and so on. This is an important source for converting energy from one form to another while utilizing electromagnetic induction. This phenomenon is efficient when the induced magnetic field is introduced

Anisotropic Diffusion in Mesh-Free Numerical Magnetohydrodynamics [PDF]

open access: yes, 2016
We extend recently developed mesh-free Lagrangian methods for numerical magnetohydrodynamics (MHD) to arbitrary anisotropic diffusion equations, including: passive scalar diffusion, Spitzer–Braginskii conduction and viscosity, cosmic ray diffusion ...
