Evidence of Critical Balance in Kinetic Alfven Wave Turbulence Simulations

, 2011
A numerical simulation of kinetic plasma turbulence is performed to assess the applicability of critical balance to kinetic, dissipation scale turbulence. The analysis is performed in the frequency domain to obviate complications inherent in performing a

The driving of turbulence in simulations of molecular cloud formation and evolution [PDF]

, 2017
Molecular clouds are to a great extent influenced by turbulent motions in the gas. Numerical and observational studies indicate that the star formation rate and efficiency crucially depend on the mixture of solenoidal and compressive modes in the turbulent acceleration field, which can be quantified by the turbulent driving parameter b.

Time-Dependent Dynamics of the Corona [PDF]

arXiv, 2023
We present in this Letter the first global comparison between traditional line-tied steady state magnetohydrodynamic models and a new, fully time-dependent thermodynamic magnetohydrodynamic simulation of the global corona. The maps are scaled to the approximate field distributions and magnitudes around solar minimum using the Lockheed Evolving Surface ...

Kinetic Turbulence

, 2015
The weak collisionality typical of turbulence in many diffuse astrophysical plasmas invalidates an MHD description of the turbulent dynamics, motivating the development of a more comprehensive theory of kinetic turbulence.

Sustainable Thermal Solutions: Enhancing Heat Transfer with Turbulators and Nanofluids

Advanced Energy and Sustainability Research, Volume 6, Issue 5, May 2025.
Nanofluids, which are nanoparticle suspensions in base fluid, facilitate heat transmission due to their improved thermal conductivity. Turbulators, which are inserts into fluid flow channels, disturb the flow, increasing turbulence and hence the heat transfer rate.

Global Alfven Wave Heating of the Magnetosphere of Young Stars [PDF]

, 2002
Excitation of a Global Alfven wave (GAW) is proposed as a viable mechanism to explain plasma heating in the magnetosphere of young stars. The wave and basic plasma parameters are compatible with the requirement that the dissipation length of GAWs be ...

Numerical Modeling of MHD Double‐Diffusive Convection and Entropy Generation in an Inclined Curvilinear Lid‐Driven Cavity

Energy Science &Engineering, Volume 13, Issue 5, Page 2297-2314, May 2025.
Numerical analysis of double‐diffusive convection in a curvilinear cavity with SiO2/H2O nanofluid, focusing on mesh, validation, results, and optimisation. ABSTRACT This paper investigates numerically the effect of MHD and entropy generation on double‐diffusive combined convection in an inclined enclosure filled with Si2O/H2O and heated fins.

Magnetic flux pumping in 3D nonlinear magnetohydrodynamic simulations

, 2017
A self-regulating magnetic flux pumping mechanism in tokamaks that maintains the core safety factor at $q\approx 1$, thus preventing sawteeth, is analyzed in nonlinear 3D magnetohydrodynamic simulations using the M3D-C$^1$ code. In these simulations, the
