FIG. 10: Same as in Fig. 8, but for large Pm = 100 and conducting boundary conditions. The parameters (β,Ro,Ha,Re) are the same as in Fig. 7(b) and the axial wavenumber is kzm = 141, corresponding to the maximum growth rate (peak on the blue curve in that panel) for the given values of these parameters. For the sake of comparison of the eigenfunction structures and lengthscales with those at small Pm, the z-axis has the same range as in Figs. 8 and 9. At large Pm, the eigenfunctions in the presence of insulating boundaries are in fact identical to the ones for the conducting boundaries shown here at the same values of the main parameters and hence we do not plot those eigenfunctions.
