Two-particle dispersion in anisotropic MHD turbulence

ASCII data for Figure 3 from the 2020 paper 'Lagrangian Statistics for Dispersion in Magnetohydrodynamic Turbulence' by J. Pratt, A. Busse, and W.-C. Mueller. The data shows the evolution of mean-square relative dispersion for particle pairs in three simulated turbulence regimes: homogeneous isotropic Navier-Stokes, homogeneous isotropic MHD, and homogeneous anisotropic MHD. Time values are provided with Figure 1 from the same publication.

Use Cases

• Analyzing the scaling of particle pair separation over time based on the mean-square relative dispersion data.
• Comparing dispersion behavior in isotropic Navier-Stokes turbulence versus isotropic and anisotropic MHD turbulence as described in the simulation results.
• Investigating the anisotropic effects of a mean magnetic field on dispersion by comparing data for initial separations perpendicular and parallel to the field.
• Validating numerical models of Lagrangian turbulence statistics against published simulation data.

Strengths

• Data is directly extracted from a peer-reviewed scientific publication (Pratt, Busse, Mueller 2020), providing a clear academic provenance.
• The description specifies comparisons across three distinct physical simulation regimes (HNOVIS, ANOVIS0, ANOVIS3).
• Data captures dispersion for specific initial conditions, including separation distance of 2 eta_kol and alignments relative to the magnetic field.

Limitations

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