Local and global properties of energy transfer in models of plasma turbulence

The nature of the turbulent energy transfer rate is studied using direct numerical simulations weakly collisional space plasmas. This done comparing results obtained from hybrid Vlasov–Maxwell collisionless plasmas, Hall magnetohydrodynamics and Landau fluid models reproducing low-frequency kinetic effects, such as damping. In this scenario, estimates local global scaling properties different channels are a proxy transfer. approach provides information on structure fluxes, under assumption that cascade transfers most then dissipated at small scales by various processes in these kinds
