Stability of the interface between two immiscible fluids in porous media. <i>Electronic Journal of Differential Equations, 2003</i>(25), pp. 1-10.1072-6691https://hdl.handle.net/10877/12691A generalized model has been recently proposed in [3] to describe deformations of the mobile interface separating two immiscible and compressible fluids in a deformable porous medium. This paper deals with a few applications of this model in realistic situations where it can be supposed that gravity perturbations are propagating much slower than elastic perturbations. Among these applications, one can include the classical well-known case of groundwater flow with free surface, but also more complex phenomena, as gravitational instability with finger growth.Text10 pages1 file (.pdf)enAttribution 4.0 InternationalPorous mediaTwo-phase flowInterfaceInstabilityArticleThis work is licensed under a Creative Commons Attribution 4.0 International License.
