Abstract
We propose in this paper a comparison of methods to parametrize the dissipative small scales in numerical simulation of MHD turbulent flow. These methods are tested against direct numerical integration of the MHD equations, in the case of homogeneous incompressible turbulence. Their efficiency to reproduce the main energetic quantities together with the geometry of the flow is discussed.
