Edson SoaresFrom July 2018 to June 2019, IFPEN-Lyon hosted Edson Soares, Professor from the Mechanical Engineering Department of the Universidade Federal do Espírito Santo (Brazil).
As a specialist in the field of fluid mechanics and the rheological characterization of complex fluids, he worked on multiphase problems, particularly those related to water treatment and water/oil separation in EOR (Enhanced Oil Recovery) processes, using experimental and modeling tools.

Professor Edson Soares was hosted at IFPEN-Lyon by a research team from the Applied Physical Chemistry and Mechanics Division: Myriam Darbouret, Guillaume Vinay and Jean-Lou Pierson. During his year-long scientific visit, he worked on the deformation and coalescence of Newtonian drops, in both Newtonian and non-Newtonian (viscoplastic and viscoelastic) fluids, in order to gain a better understanding of water/oil interface stability and hence be able to improve the different types of equipment used to separate a mixture of these two fluids.

Professor Edson Soares of his time working alongside Jean-Lou Pierson, an expert in multi-phase flows, and with Hiranya Deka, a post-doctoral researcher at IFPEN since January 2019, on:

  • a review of the existing literature on drop’s stretching and break-up in non-Newtonian fluids, 
  • the testing and validation of non-Newtonian models in the Basilisk open source code,
  • the simulation and analysis of various associated problems of significance.
    .

The research will lead to several publications relating to the following themes: viscous droplet retraction,  viscoplastic sheet retraction, the stretching and retraction of Newtonian and non-Newtonian drops in viscous fluids and the coalescence of viscous droplets in a polymer solution.
