Single Particle Diffusion in Anisotropic MHD Turbulence: Lagrangian Statistics

ASCII data for Figure 1 from Pratt, Busse, Mueller 2020. The data shows the evolution of mean-square distance from initial positions for particles in three simulated turbulence regimes: incompressible isotropic hydrodynamic, isotropic magnetohydrodynamic, and anisotropic magnetohydrodynamic. Each curve is produced from the average of at least 4 independent initial times.

Use Cases

• Modeling particle diffusion in anisotropic magnetohydrodynamic turbulence based on the described mean-square distance curves.
• Comparing Lagrangian statistics between isotropic hydrodynamic and magnetohydrodynamic turbulence regimes as described.
• Analyzing the separation of particle motion parallel and perpendicular to a mean magnetic field, as detailed for the ANOVIS3 simulation.

Strengths

• Data is derived from a published 2020 research paper, providing a direct link to peer-reviewed science.
• Each statistical curve is averaged from at least 4 independent initial times, suggesting a measure of statistical robustness.
• The description explicitly compares three distinct physical simulation regimes (HNOVIS, ANOVIS0, ANOVIS3).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Last update date is unknown; freshness unverified.
