European training network on control prediction and learning in mixing processes

The CoPeRMix network brings together a collection of experts at the European scale from academia and industry, who have all adopted new angles of attack to the problem of mixing according to their needs and fields of application, in order to foster the emergence of a unified viewpoint, through intensive collaboration between different schools of thought and methods. This effort builds up on existing collaborations between several participants, and lectures or courses delivered by some of us in various university curricula in their own institution, and abroad. More precisely, this training network is the emanation of the “Mixing Days” organized by the consortium on a yearly basis (Marseille in 2016, Rennes in 2017, Barcelona in 2018 and Brussels in 2019), which have been the opportunity to conceive and share a new methodology: the lamellar description of mixing.
It consists in viewing a mixture as a set of elongated lamellae and sheets and understanding how they are stretched and dispersed by the stirring flow. This first step provides the necessary information to address the stirring/molecular diffusion coupling, leading to the complete statistical description of the mixing process i.e. the full concentration distribution. This disruptive vision has prompted new numerical (Diffusive Strip Method) and experimental methods. They offer an unprecedented opportunity of accurately describe Stirring protocols which is the ground to understanding and model- ling Mixing and its Impact in a diversity of fields. This lamellar description of mixing provides a consistent and invertible theoretical framework giving us also the opportunity to Learn from mixed scalar fields.

Very promising outcomes are expected as the CoPerMix programme unites leading academic and industrial partners with a broad expertise in the fundamentals and applications of mixing in a very wide range of fields.

A new upscaling approach for multiphase flow, mechanical deformation, and hydrodynamic transport in permeable media

The main objective of the project is to uncover and quantify the mechanisms and laws that govern multiphase flow, mechanical deformation and hydrodynamic transport in permeable media, from the pore to the regional scales. To achieve this goal, HydroPore proposes a multidisciplinary and integrated research strategy that combines a new theoretical upscaling framework with novel experimental protocols and cutting-edge numerical simulation techniques
