MRI Turbulence at High Reynolds Numbers

POSTER

Abstract

The properties of magnetic turbulence driven by the magnetorotational instability (MRI) are studied at large Reynolds numbers by simulation. The results are compared with previous published results at lower Reynolds number and with forced magnetohydrodynamic (MHD) turbulence. Preliminary results suggest that spectra exhibit a power law within a short inertial range, and similarities and differences with the inertial range in MHD turbulence are established.
