Nonlinear closures for scale separation in supersonic magnetohydrodynamic turbulence

Grete, Philipp; Vlaykov, Dimitar G; Schmidt, Wolfram; Schleicher, Dominik R G; Federrath, Christoph

Description

Turbulence in compressible plasma plays a key role in many areas of astrophysics and engineering. The extreme plasma parameters in these environments, e.g. high Reynolds numbers, supersonic and super-Alfvenic flows, however, make direct numerical simulations computationally intractable even for the simplest treatment—magnetohydrodynamics (MHD). To overcome this problem one can use subgrid-scale (SGS) closures—models for the influence of unresolved, subgrid-scales on the resolved ones. In...[Show more]
