There has been great recent interest in dynamic models of multi-phase flow. This is for two reasons: one, theoretical arguments suggest that the traditional multi-phase flow equations are not complete; two, various experimental measurements are unable to be described by the traditional models. In this talk, we discuss the observation that constant flux infiltrations into sands produce non-monotonic saturation and pressure profiles. We show how this non-monotonic behavior is the strongest evidence of dynamic effects in porous media, as other reported experimental evidence can be the result of varying measuring volumes, and/or media heterogeneities. Thus the extensive data set obtained for these non-monotonic provides the best testing ground for the various proposed dynamic extensions.

Сформулированы и доказаны принципы максимума для нескольких моделей многофазной фильтрации. Первый принцип справедлив для фазовых насыщенностей в несжимаемом случае модели двухфазной фильтрации с постоянными вязкостями, а второй - для глобального давления в моделях двух- и трехфазной фильтрации Two maximum principles for several multi-phase flow models are formulated and proved. The first one is valid for phase saturations in an incompressible two-phase flow model with constant viscosities. The second one is valid for the global pressure in two- and three-phase flow models with constant viscosities and is also valid for phase pressures in the case of zero capillary pressure.
