Astrophysical flows span a broad range of scales and thus require sub-grid modeling. We compute the energy fluxes in the Fourier and physical space for the turbulent magnetized shearing box simulations with a weak net vertical magnetic flux. The energy fluxes are dominated by the injection term from the mid-to-large scale range due to the Reynolds and Maxwell stresses in both cases while the small scales are dominated by dissipation. Since the nature of turbulent cascades requires a clear separation of scales, our work is unable to address these questions conclusively. But because our work is the first of its nature in trying to connect the Fourier and physical space energy flux behavior, we are able to make connections between the two profiles.
