Comparison of potential terms of the convective flux equation of the 3-equation model as a function of radius. The results of the sim_k and sim_m simulation are shown with a yellow and green line, respectively. The potential terms of the convective flux equation obtained from the 3-equation model are shown with the remaining coloured lines (see legend for details). The parameters α_ω, α_Π and α_Φ are varied in the upper, middle and lower panel respectively. The mid-blue line indicates the default parameter values.
