摘要: Magnetohydrodynamic (MHD) turbulence is an intrinsic part of astrophysical phenomena, which plays a crucial role the generation cosmic magnetic fields. The two-scale dynamo concept suggests that small scale interactions are demanded to drive large fields planets, stars and galaxies. Since experimental study MHD almost impossible numerical simulation only way verify theoretical ideas phenomenology. purpose this work demonstrate possibilities direct using TARANG code (open source software). We focus on mathematical formulation built-in postprocessing functions for analysis spectral distributions transfers energies helicities in forced 3D homogeneous isotropic turbulence.
