Abstract
In this chaper we address the problem of nonlinear stability for thermal convection in a system which consists of \(N\) identical horizontal porous layers of the same thickness interleaved with \(N-1\) identical layers of a rigid heat conducting solid each of the same thickness, where \(N\) is an integer greater than or equal to 2. The temperatures of the upper surface of the top layer, at \(z=H\), and lower surface of the bottom layer, at \(z=0\), are fixed at constant values \(T_U\) and \(T_L\), respectively, with \(T_L>T_U\). The key parameters governing the behaviour of the solution to the instability problem are the ratio of the depth of rigid solid to the depth of porous layer, \(\delta \), and the ratio of the thermal conductivity of the solid to the thermal conductivity of the porous material, \(d\), and the number of porous layers, \(N\). The porous materials are allowed to be of Darcy type or Brinkman type and the permeability may be anisotropic.
