Fluid mechanics phD position at HydEE team

[TheChamp-Sharing]
Numerical modelling of fluid/structure interaction in the porous layer.

The performance of many industrial applications is largely based on the quality and reliability of the guidance and support systems (high rotational speeds, low friction torque, damping capability, etc.). The subject of the Phd thesis presented here is part of a ANR (Agency National Research) french project, entitled SOFITT (Saturated Open-pore Foams for Innovative Tribology in Turbomachinery) and aiming at finding innovative technical solutions that break with current practices and provide high-performance support systems in terms of load capacity and damping. The project proposes a new concept of lubrication and correspondingly a new material (understood as a complex/composite material formed by the solid porous structure – compressible porous layers – and the imbibing fluid) in order to improve the quality and reliability of the guidance and supporting systems. The CFD (Computational Fluid Dynamics) simulations offer an economical solution to study the performance of this new concept of lubrication. During the Phd thesis, two predictive models will be developed to study the response to external stresses of liquid-soaked compressible materials, in particular by estimating their load and damping capacities.

Expert in Scientific Computation

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

Very high performance optical treatments via PVD (Physical Vapor Deposition) deposition techniques in OAD geometry (Oblique Angle Deposition)

Le projet ARCHITEC est centré sur le développement de traitements optiques « très haute transmission » (traitements antireflets) via la technique de fonctionnalisation de films minces en géométrie OAD. Cette technique offre la possibilité de contrôler, grâce à un effet d’ombrage, la porosité des films et par conséquent leur indice de réfraction... Profil: Dans ce contexte, nous souhaitons recruter un expérimentateur avec une bonne expertise en physique de la matière condensée notamment dans le domaine des films minces ; domaine incluant leur croissance, leur caractérisation structurale et l’étude de leurs propriétés physiques...
