Coronal Loop Heating by Nearly Incompressible Magnetohydrodynamic and Reduced Magnetohydrodynamic Turbulence Models [PDF]

open access: yesarXiv, 2023
The transport of waves and turbulence beyond the photosphere is central to the coronal heating problem. Turbulence in the quiet solar corona has been modeled on the basis of the nearly incompressible magnetohydrodynamic (NI MHD) theory to describe the transport of low-frequency turbulence in open magnetic field regions.

Athena: A New Code for Astrophysical MHD [PDF]

open access: yes, 2008
A new code for astrophysical magnetohydrodynamics (MHD) is described. The code has been designed to be easily extensible for use with static and adaptive mesh refinement.

Dynamic Alignment and Exact Scaling Laws in MHD Turbulence

open access: yes, 2009
Magnetohydrodynamic (MHD) turbulence is pervasive in astrophysical systems. Recent high-resolution numerical simulations suggest that the energy spectrum of strong incompressible MHD turbulence is $E(k_{\perp})\propto k_{\perp}^{-3/2}$. So far, there has

MHD Heat Transfer Enhancement in a Curvilinear Enclosure With Oscillating Wall and Nano‐Encapsulated PCM: A Fluid‐Structure Interaction Analysis

open access: yesHeat Transfer, EarlyView.
ABSTRACT Thermal management systems integrating phase change materials face challenges in maximizing heat transfer efficiency for electronics cooling and energy storage applications. This study addresses the research gap regarding fluid‐structure interaction and magnetohydrodynamic effects on nano‐encapsulated PCM performance in complex geometries.

A Comparative Study of Velocity Statistics of Hydrodynamic and Magnetohydrodynamic Turbulence [PDF]

open access: yesarXiv, 2006
Turbulence in an incompressible fluid with and without a magnetic field as well as moderately compressible MHD turbulence are compared. For the magnetohydrodynamic (MHD) models the probability distribution functions of the velocity components perpendicular to the external magnetic field are like the incompressible hydrodynamic (HD) model while those ...

Incompressible MHD Turbulence [PDF]

open access: yesInternational Astronomical Union Colloquium, 2001
AbstractThe inertial range of incompressible MHD turbulence is most conveniently described in terms of counter propagating waves. Shear Alfvén waves control the cascade dynamics. Slow waves play a passive role and adopt the spectrum set by the shear Alfvén waves.

How statistically fragile are randomized controlled trials comparing quadriceps tendon autografts with hamstring or bone‐patellar tendon‐bone autografts in anterior cruciate ligament reconstruction?

open access: yesKnee Surgery, Sports Traumatology, Arthroscopy, EarlyView.
Abstract Purpose To determine the statistical fragility of randomized controlled trials (RCTs) which compare the use of quadriceps tendon (QT) autografts to either hamstring tendon (HT) or bone‐patellar tendon‐bone (BPTB) autografts in anterior cruciate ligament reconstruction (ACLR).

A note on the inviscid limit of the incompressible MHD equations [PDF]

open access: yesarXiv, 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 ...
