Base model for a phase
Information
The scaling factor for diffusive transport (k) is a vector which directly affects the resistance associated with the transport of material, transverse translational momentum, and energy of all of the species within the phase. It can be used to introduce minor head loss or the effects of porosity or tortousity. These effects may be anisotropic. Using Bruggeman correction [Weber2004, p. 4696], the factor (k) within a phase should be set to ε-1/2 along each axis, where ε is the volumetric filling ratio, or the ratio of the volume of the phase to the total volume of the subregion. The Bruggeman factor itself increases resistance by a ε-3/2, but a factor of ε-1 is included inherently.
