摘要

In porous media theories the volume fractions are introduced as internal variables. While for incompressible constituents the evolution of the volume fractions follows from the balance of mass, for mixtures with compressible constituents additional equations are required, which must be given constitutively. In the present contribution, an evolution equation is postulated and a related two-phase model is examined.
