Offre de Post Doc : Pore-scale modelling of two-phase flows in highly permeable porous structures

Pore-scale modelling of two-phase flows in highly permeable porous structures

Duration The offer is for 12 to 18 months.

The physics of two-phase flows in materials with pores larger than a few millimetres is significantly different from that of materials with smaller pores. Capillarity, for example, may play a much weaker role so that viscous, inertial and gravitational effects may dominate the flow. Modelling these systems is a considerable challenge since most models developed in porous media sciences, such as the generalized Darcy’s law, implicitly assume that capillarity is important. An important consequence of this is the absence of direct coupling forces between the two phases in the generalized Darcy’s law. In our group, we are studying two-phase flows within structures with centimetre-sized pores in a wide variety of applications, ranging from flows in structured packings used in distillation columns to geophysical media or PWR nuclear reactor cores in normal or accidental conditions. We have developed a joint expertise, experiments and collaborations with IRSN (radioprotection and nuclear safety institute), CEA (atomic energy commission), BRGM (geological and mining research bureau) or the company Air Liquid. The PDRA will be in direct collaboration with 3 PhD theses currently going on with IRSN, CEA and BRGM.
