Dr. Tom Bultreys, winner 2019 of the InterPore – PoreLab Award for Young Researchers – Congratulations!

By PoreLab19 February, 2019Awards, InterPore

Dr. Tom Bultreys, from Ghent University, Belgium, has contributed significantly to the field of pore-scale imaging and modeling. During his PhD, he developed a multi-scale network model to describe rocks with a very wide range of pore sizes. New concepts were developed, which have already found commercial applications. In his subsequent work at Imperial College,

On June 12th, Tran Quoc-Anh, Ph.D student in Computational Geomechanics from the Department of Civil Engineering at Aalto University, Espoo, Finland, will present a research proposal regarding “Landslides investigation and consequences”. Please note that the meeting will be held on skype.

The title and abstract for the presentation is:

Abstract:

Landslides are a serious natural hazard common to many regions in Europe. From 1995 to 2014, 476 landslides were reported in Europe with a total of 1370 deaths and 784 injuries and an average economic loss of approximately 4.7 billion euros per year. It is important to estimate potential landslides and their consequences. However, modelling the landslides is a long-standing challenge as it involves the triggering mechanism (rainfall, erosion or human-made activities), the onset of failure and post-failure mechanism such as run-out distances. Therefore, it requires advanced numerical approaches to be capable of simulating large deformation problems as well as an advanced constitutive model to consider the solid-fluid transition behavior.

Antoine will also apply for a Marie Curie grant and will present his proposal before the group on Thursday, before the journal club.
The title and definition of the project is:

On June the 18th, Professor Majid Hassanizadeh, Managing Director at InterPore and Professor of Hydrogeology at Utrecht University, will give a talk on “Advanced theories of two-phase flow in deformable porous media; experimental and computation studies”.

Abstract:

Two-phase flow in porous media is traditionally modeled using a modified form of Darcy’s law, two volume balance equations, and a so-called capillary pressure-saturation relationship. Darcy’s Law was proposed more than 150 years ago for the flow of a single fluid in soil. Since then, this equation, in almost original form, has been assumed to be applicable to more and more complicated porous media. But, there are many shortcomings of the so-called extended Darcy’s Law. Also, the empirical relationship between capillary pressure and saturation is known to suffer from some important shortcoming (it is hysteretic and may depend on the rate of flow or rate of change of saturation).

In this lecture, we present a new theory of two-phase flow, which comprises a truly extended Darcy’s law and a new capillarity theory, which has five main features: i) pressure gradient is not the only driving force, ii) saturation and pressure are not the only state variable; fluid-fluid interfacial area is another state variable, iii) capillary pressure is an intrinsic property of the porous medium and is not only a function of saturation but also fluid-fluid specific interfacial areas, iv) effective stress parameter is a function of fluid-fluid specific interfacial area as well as saturation, and v) there is a dynamic (or non-equilibrium) capillarity effect. We provide experimental evidences for the validity of the new theory. Also, pore-scale and continuum-scale simulations are used to study the possible significance of the new theory at various scales.

On June the 25th, Professor Majid Hassanizadeh, Managing Director at InterPore and Professor of Hydrogeology at Utrecht University, will give a talk on “Capillarity in porous media at different scales”

Abstract:

In this lecture, current definitions of capillary pressure, which are mostly empirical in nature are revisited and it is shown that they are special cases of a more general theory of capillarity. In particular, capillary pressure is defined at pore scale based on equations of momentum conservation for interfaces. It is shown that in general, capillary pressure is equal to the difference in pressures of the two fluids only under static conditions. For dynamic conditions, a non-equilibrium capillarity equation is derived. Based on results of experimental studies, it is shown the current working assumption that capillary pressure is a function of saturation is grossly deficient. In this regard, the role of fluid-fluid interfaces in the characterization of capillarity is elucidated. Computational and experimental studies are presented that highlight the value of new generalized capillarity theory.
