  Determination of the aperture distribution of rough-walled rock fractures with the non-toxic Yield Stress fluids porosimetry method 

  RODRIGUEZ DE CASTRO, Antonio; AHMADI-SENICHAULT, Azita; OMARI, Abdelaziz (Elsevier BV, 2020-12)

  Fractures in geological formations constitute high-conductivity conduits which potentially act as preferential paths during fluid injection in soil remediation and reservoir engineering operations. Recently, the measurement ...

  Experimental and numerical upscaling of foam flow in highly permeable porous media 

  OMIRBEKOV, Sagyn; DAVARZANI, Hossein; COLOMBANO, Stéfan; AHMADI-SENICHAULT, Azita (Elsevier BV, 2020-12)

  Foam in porous media has been studied as a tool for various applications. Recently, the technology has become relevant for contaminated-aquifer remediation, where porous media are highly permeable. Therefore, the behavior ...

  Numerical porosimetry: Evaluation and comparison of yield stress fluids method, mercury intrusion porosimetry and pore network modelling approaches 

  RODRIGUEZ DE CASTRO, Antonio; AGNAOU, Mehrez; AHMADI-SENICHAULT, Azita; OMARI, Abdelaziz (Elsevier BV, 2020-02)

  Mercury Intrusion Porosimetry (MIP) is still today the reference porosimetry technique despite its environmental health and safety concerns. As a safe alternative, the Yield Stress fluids Method (YSM) consists in computing ...

  Three-dimensional microscale simulation of colloidal particle transport and deposition in chemically heterogeneous capillary tubes 

  LI, Yajie; AHMADI-SENICHAULT, Azita; OMARI, Aziz; PU, Hongting (Elsevier BV, 2020-02)

  The effect of surface chemical heterogeneity and hydrodynamics on particle transport and deposition in porous media was investigated by microscale simulations using a colloidal particle tracking model, called 3D-PTPO ...

  Non-Fickian dispersivity investigation from numerical simulations of tracer transport in a model double-porosity medium at different saturations 

  TRAN NGOC, T.D.; AHMADI-SENICHAULT, Azita; BERTIN, Henri (Elsevier BV, 2020-10)

  It is generally admitted that dispersivity is an indicator of the heterogeneity scale of porous media. This parameter is assumed to be an intrinsic property which characterizes the dispersive behavior during the transport ...

  Experimental Study of Non-Newtonian Behavior of Foam Flow in Highly Permeable Porous Media 

  OMIRBEKOV, Sagyn; DAVARZANI, Hossein; AHMADI-SENICHAULT, Azita (American Chemical Society (ACS), 2020-06-26)

  Foam-flow behavior in highly permeable porous media is still unclear. Two types of pregenerated foam using porous columns filled with fine sand and 1 mm glass beads were studied in different packs of glass beads with ...

  Homogenization of Solute Transport in Unsaturated Double-Porosity Media: Model and Numerical Validation 

  TRAN NGOC, T. D.; LE, Nam H. N.; TRAN, Tieng V.; AHMADI-SENICHAULT, Azita; BERTIN, Henri (Springer Science and Business Media LLC, 2020-01-23)

  The development of a macroscopic model for solute transport coupled with unsaturated water flow in double-porosity media is presented in this work, by using the asymptotic homogenization method. The model was derived for ...
