In the marginal stability analysis, changing the parameters, e.g. geometrical constraints and viscosity, we find that there are two modes of coupling between the upper and lower convecting fluids as was previously pointed out by Ukaji and SAWADA (1970 a, b, 1971). The first is the\u0027mechanical coupling\u0027in which the horizontal component of the velocity near the interface between two fluids runs in the same direction. The second is the \u0027thermal coupling\u0027in which the horizontal component of the velocity near the interface runs in the opposite direction. If one of the two fluids becomes more unstable, it drags the other. This is clearly a modified \u0027mechanical coupling\u0027mode which we tentatively call the \u0027dragging mode\u0027. The thermal coupling may be a more excited state than the \u0027mechanical coupling\u0027. Several stability curves obtained by the analysis can be roughly explained in terms of the instability in each layer. In the study of the finite amplitude convection with the infinite Prandtl number, we calculate the Nusseldt number, temperature, stream function and vorticity for various Rayleigh numbers for three kinds of models. The calculated Nusseldt number-Rayleigh number relations are explained by a simple parameterized analysis in spite of the non-linear nature of the problem. This parameterization is possible because the interface between the two immiscible fluids is a plane of almost zero shear stress and the temperature at the interface is nearly constant. Thus, the efficiency of the heat transport can be estimated as follows; 1) calculate \u0027local\u0027Rayleigh numbers defined for each layer. 2) assume that the Nusseldt number-\u0027local\u0027Rayleigh number relation for each layer is the same as that of \u0027one\u0027layer. 3) formulate the equation of continuity of the heat flux at the interface. As a result of procedure (3), we can obtain the temperature at the interface and also the total heat flux flowing through the convection system. Well developed thermal boundary layers are formed at the top and bottom surfaces and the interface, when appropriately defined Rayleigh number many times exceeds the critical Rayleigh number. All the flow fields obtained in the study of the finite amplitude convection are of the \u0027mechanical coupling\u0027mode. This mode may exist in the mantle, if the mantle consists of several independently convecting layers.", "subitem_description_type": "Abstract"}, {"subitem_description":
