(M)HD turbulence synthesis for astrophysics
Abstract
An analytical model for 3D incompressible turbulence was recently introduced in the hydrodynamics community which, with only a few parameters, shares many properties of experimental and numerical turbulence. In our work, we extend this approach to compressible and magnetized fluids, in view of modeling astrophysical environments. Such analytical models constitute a complementary tool to numerical simulations, as they enable us to generate very quickly fairly realistic synthetic data (density, velocity and magnetic fields coupled together), the statistics of which are controllable with intuitive parameters. In this talk, I will present the main ideas behind such modeling.
