| Abstract: | ![]()
The capillary hysteresis in a dynamic and quasi-static two-fluid flow in a porous medium is discussed. Thermodynamic background is presented. It is shown that physically acceptable constitutive relations satisfying the thermodynamic conditions can be constructed in terms of Preisach hysteresis operators. |
