CG analysis of the cross helicity: Validity test of the isotropic CG 𝒪_Hcl, Eq. (B.13), as a function of k at tΩ_i = 700 (black line) along with the different contributing terms: decay rate ∂_tH_cl (blue), MHD cascade rate Π_Hcl (green), resistive dissipation rate 𝒟_Hcl (red), and pressure-strain rate Φ_Hcl (magenta). All the quantities are given in units of the total (effective) cross-helicity dissipation rate ϵ_Hc.
