Onset of convection in a couple-stress fluid-saturated porous medium: effects of non-uniform temperature gradients

Onset of convection in a layer of couple-stress fluid-saturated porous medium is investigated for different types of basic temperature gradients. The boundaries are considered to be adiabatically insulated to temperature perturbations.
