NON-LINEAR THERMAL-CONVECTION IN ANISOTROPIC POROUS-MEDIA

In this paper a theoretical investigation of convection currents in anisotropic porous media is performed. The porous layer is homogeneous and bounded by two infinite perfectly heat-conducting horizontal planes. The criterion for the onset of convection is derived. The supercritical steady two-dimensional motion, the heat transport and the stability of the motion are investigated. Some of the results may be applied in insulation techniques. © 1979, Cambridge University Press. All rights reserved.
