Equivalent vs effective properties of heterogeneous porous formations

Equivalent-vs-effective-properties-of-heterogeneous-porous-formations New concepts of equivalent/apparent properties are defined to characterize the mean flow in heterogeneous porous formations. Unlike the effective properties (valid only for flows uniform in the mean), the equivalent ones are shown to be useful in those applications where flow is not uniform in the mean.
