We show that the global nonlinear stability threshold for convection in a couple-stress fluid is exactly the same as the linear instability boundary. This optimal result is important because it shows that linearized instability theory has captured completely the physics of the onset of convection. I
An accurate numerical analysis for the onset of thermal convection in a twolayer system is presented. The system comprises a saturated porous layer over which lies a layer of the same fluid. The layered system is heated from below, the upper (fluid) surface is free to the atmosphere, and convection
