We are excited to announce the TSVP Thematic Program "Multiphase flows in multiscale porous media: Modeling, simulations and asymptotic".
Title: Multiphase flows in multiscale porous media: Modeling, simulations and asymptotic
Theme of the program: The problem of multiphase flow in porous media is of paramount importance in a vast area of applications such as oil/gas recovery from hydrocarbon reservoirs, carbon dioxide sequestration in geological formation, subsurface remediation of organic contaminants, regenerative medicines, nutrient transport in articular cartilage, turbulent canopy flows. A porous medium consists of a solid matrix of interstices by a void phase represented by its porosity. Multiphase flows in porous media represent fluid flow problems of significant complexity involving a wide range of physical problems and multiple scales (both length and time). The later imposes challenges in understanding fluid flow and solute transport through a porous medium. This thematic program will focus on modelling, simulations, and asymptotic aspects of multiphase and reactive flows in rigid as well as deformable porous media involving multiple scales.

Tentative Schedule
Week 1-2: Fundamentals. The first two weeks will focus on fundamentals of porous media, multiphase, and multiscale flows. The activities will consist of lectures on classical theories of flow and transport in porous media at Darcy scale, multiphase, and multiscale flows in general as well as sessions for roundtable discussions on related topics. The lectures and the discussions will be scheduled in such a way that the participants as well as the members of OIST will have scope for one-to-one interactions.
Week 3-4: Modelling, simulations and asymptotic. When a fluid carrying a passive solute flows through porous media, several key macroscale transport mechanisms occur depending on the speed of the fluid. Understanding these transport mechanisms in heterogeneous porous media is challenging due to multiscale nature of the flow. A multiphase flow in a heterogeneous porous media carrying a solute that may influence the physical properties (e.g., viscosity and/or density) of the fluid imposes more complexity and challenges. Asymptotic analysis of mathematical model describing multiphase flow and transport in multiscale porous media helps to better understand the underlying physics. Week 3-4 will focus on modelling, simulations and asymptotic of flow and transport in porous media.
Week 5: Symposium. The symposium will feature four talks per day, two in the morning and two in the afternoon in the first four days of the symposium. Only two talks in the morning session will be held on the last day of the symposium. The scientific talks will cover theoretical, computational, and experimental advances in porous media flow with a focus on multiscale aspects. A round-table discussion encouraging early- career researchers to share their ideas will be organized during the afternoon session of the fifth day of the symposium. The round-table will also cater to provide broader view to young researchers of how this research impacts industrial applications and environmental challenges, fostering collaboration between academia and industry.
Week 6: Applications, Discussion meetings and Outreach activities. Week 6 will be devoted to discuss applications of multiphase porous media flows, as well as outreach activities (career talks, public lecture).
