| Abstract: | Based on the procedure of (Gray & Hassanizadeh 1998) we state macroscale conservation equations
for multi phase flow in porous media including interfacial area as a variable. The phases we consider are a
solid phase, a wetting phase and a non-wetting phase. Some modeling work is done to decide the functionality
of the coefficients in the equations. In particular we construct constitutive relationships for the interfacial area
as a function of saturation and capillary pressure, and the resistance terms. The final set of equations is reduced
to a 2 x 2 system with the saturation and the interfacial area as independent variables. Some preliminary
numerical experiments are reported. |
