Global simulations of magnetorotational turbulence-ii. turbulent energetics

Parkin, Elliott

Description

Magnetorotational turbulence draws its energy from gravity and ultimately releases it via dissipation. However, the quantitative details of this energy flow have not been assessed for global disc models. In this work we examine the energetics of a well-resolved, three-dimensional, global magnetohydrodynamic accretion disc simulation by evaluating statistically averaged mean-field equations for magnetic, kinetic and internal energy using simulation data. The results reveal that turbulent...[Show more]
