Post-Newtonian Magnetohydrodynamics [PDF]
arXiv, 2020 Using the fully nonlinear and exact perturbation formulation with magnetohydrodynamics (MHD) in Minkowski background we derive first-order post-Newtonian (1PN) equations without imposing the slicing (temporal gauge) condition. The 1PN MHD formulation is complementary to our recently presented fully relativistic MHD combined with 0PN gravity available ...

Trans-Magnetosonic Accretion in a Black Hole Magnetosphere
, 2002 We present the critical conditions for hot trans-fast magnetohydrodynamical (MHD) flows in a stationary and axisymmetric black-hole magnetosphere. To accrete onto the black hole, the MHD flow injected from a plasma source with low velocity must pass ...

A note on the inviscid limit of the incompressible MHD equations [PDF]
arXiv, 2016 In this paper, we prove that as the viscosity and resistivity go to zero, the solution of the Cauchy problem for the incompressible MHD equations converges to the solution of the ideal MHD equations in the same topology with the initial data. Our proof mainly depends on the method introduced by the paper \cite{G.L.Y} and the constructions of the ...

MHD Turbulence, Turbulent Dynamo and Applications [PDF]
, 2014 MHD Turbulence is common in many space physics and astrophysics environments. We first discuss the properties of incompressible MHD turbulence. A well-conductive fluid amplifies initial magnetic fields in a process called small-scale dynamo. Below equipartition scale for kinetic and magnetic energies the spectrum is steep (Kolmogorov -5/3) and is ...

Scaling, Intermittency and Decay of MHD Turbulence
, 2004 We discuss a few recent developments that are important for understanding of MHD turbulence. First, MHD turbulence is not so messy as it is usually believed.

Movement Disorders, EarlyView.Abstract Background The aim was to investigate if glymphatic function is impaired in patients with Huntington's disease (HD) and its clinical relevance. Methods Forty‐nine subjects carrying mutant Huntingtin (mHTT), comprising 35 manifest (mHD) and 14 pre‐manifest (PreHD), and 35 healthy controls (HC) were recruited in this study.

Unsteady hydromagnetic couette flow due to ramped motion of one of the porous plates
International Journal of Applied Mechanics and Engineering, 2013 An unsteady flow formation in Couette motion of an electrically conducting fluid subject to transverse magnetic field has been analyzed in the presence of suction/injection through the porous plates when one of the porous plates is in ramped motion.

Alias Sampling Effect on the Calculation of MHD Mode Number in Fusion Plasma [PDF]
arXiv, 2019 Detailed alias frequency formula and the effect of alias sampling on the calculation of MHD mode number are derived. It is discovered that the absolute MHD mode number/structure does not change under alias sampling. This discovery can help us to determine the structure of the high frequency MHD mode with low frequency sampled diagnostics even when the ...
