Comparison of terms neglected in the TKE equation of the Kuhfuß model as a function of radius. The upper panel shows the left hand side of the equation, the middle panels shows the shear term and the lower panel shows the pressure fluctuation terms. The results of the sim_k and sim_m simulation are shown with yellow and green lines, respectively. We indicate the entropy and TKE boundaries with dashed and dotted lines in the respective colour.
