Y. Qin et J. Chadam, NONLINEAR CONVECTIVE STABILITY IN A POROUS-MEDIUM WITH TEMPERATURE-DEPENDENT VISCOSITY AND INERTIAL DRAG, Studies in applied mathematics, 96(3), 1996, pp. 273-288
A nonlinear stability analysis of convection in a fluid-saturated poro
us medium with temperature-dependent viscosity and inertia drag is pre
sented. It is shown that the quadratic drag term is mathematically imp
ortant and physically significant in ensuring conditional stability.
