Magnetohydrodynamic Turbulence in Accretion Discs: Towards More Realistic Models

  • Ulf Torkelsson (a1), Axel Brandenburg (a2), Åke Nordlund (a3) and Robert F. Stein (a4)

Abstract

The shearing box has rapidly become the accepted way to investigate turbulence in Keplerian shear flows. In this paper we discuss to what extent and in which way the outcome of the shearing box is affected by the adopted boundary conditions, and how the shearing box can be modified to capture more of the physics of an accretion disc. The original shearing box model is too symmetric to generate a net accretion flow, but the symmetry can be broken by including the main effects of the cylindrical geometry of the real disc. However the quantitative change in the resulting angular momentum transport is small.
