[TheChamp-Sharing]
The postdoctoral intership is funded by the action 2 «Dynamique descontaminants» in the axis 3 «Chimie verte et préservation des ressources (eau,sol, biodiversité, carbone renouvelable)» of the ECONAT programme «gestiondurable des ECOsystèmes et des ressources NATurelles» (CPER 2015 – 2020). Oneobjective of the action 2 is to study the transport behavior of contaminants infractured limestone structures of the catchment area of Charente. In this action 2,we propose to develop numerical models, based on the Monte Carlo approach, forestimating the maximum dilution index Emax in heterogeneous porous andfractured media

Instability development at the interface of viscous heterocharged fluids

The proposed studies will relate to a low Reynolds laminar flow of a two-dimensional mixture layer of a highly viscous dielectric fluid. The fluid / fluid interface will be studied experimentally under different conditions. This subject is part of action 5.1 of the INTERACTIVES labex, action which concerns the manipulation of internal flow by electrical discharge and charge injection.

CLOSED-LOOP FLOW CONTROL BY PLASMA DISCHARGE AND MACHINE LEARNING

We propose to numerically derive closed-loop control strategies of different flows. We will treat the numerical simulation aspects of physical mechanisms (electrodynamics and fluid mechanics) and the development of innovative control strategies (Data Driven approaches based on machine learning methods). We will study two rather emblematic types of flows: - The flow behind an obstacle (cylinder, wing profile, backward facing step). This type of strongly separated flow is particularly interesting in cases where the objective of the control is to increase aircraft stealth.
