The coupling of multi-phase flow models

We consider here the mechanical contact problem between a periodic elastic wavy surface and a flat rigid plane (the case which was historically the starting point in the study

In order that the predicted fiber orientation captures both the correct skin–shell–core structure and a global radial evolution along the flow path, in the discrepancy function,

Experimentally, it has long been known that a non linear relationship between the flow rate and the pressure drop imposed on the porous medium is obtained for non-Newtonian fluids

The model profiles for the magnetic field, the ion temperature and density are obtained by a fit procedure (Fig. 3a, b, and c, respectively), whereas the others are calculated from

In this paper we prove the existence of a solution of a coupled system involving a two phase incom- pressible flow in the ground and the mechanical deformation of the porous

The basic idea of the coupling method is to introduce a father model, which corresponds to the two-fluid two-pressure approach, and to define convective fluxes through the

The second approach has been retained here in order to perform the coupling of a two-fluid model (which involves six governing partial differential equations in order to account
