Abstract
The Guyer–Krumhansl equation is coupled with the Cattaneo–Fox law for the temperature and heat flux fields to study thermal convection in a fluid-saturated Darcy porous material. In particular the effects of the Guyer–Krumhansl terms on oscillatory convection are studied. It is found that for a certain range of the Guyer–Krumhansl coefficient stationary convection occurs while changing the range results in oscillatory convection. Numerical results quantify this effect.
