Notice: As of 2014 and for the forthcoming years, the publication frequency/periodicity of WSEAS Journals is adapted to the 'continuously updated' model. What this means is that instead of being separated into issues, new papers will be added on a continuous basis, allowing a more regular flow and shorter publication times. The papers will appear in reverse order, therefore the most recent one will be on top.

ABSTRACT: Flow through a variable permeability Brinkman porous layer with quadratic permeability function, underlain by a Darcy porous layer of variable linear permeability function is analyzed. The model flow demonstrates the compatibility between the low-order Darcy law and the Brinkman equation in the sense that at the sharp interface between the layers it is possible to impose equality of the non-zero shear stresses. A matching procedure is also introduced for velocity computation near the point of singularity associated with the resulting Cauchy-Euler equation.
