Presentation of the establishment and the laboratory of reception:
The CEMEF is a European leader in the field of research on material processing (metals and polymers).
Approximately 160 people - including 70 PhD students are performing research
designed to get in depth understanding of forming processes. The main expertise
is on thermal, mechanical and physical modeling, numerical simulation,
processing, physics and chemical physics. In the field of polymers, the main
research areas are:
· Polymers physics: Crystallisation (quiescent, under flow), flow of suspension, polymer
rheology, dispersion of porous aggregates.
· Simulation: Modelling of the main polymer forming processes, software
development.
Injection molding (Rem3D®), extrusion (Ludovic®), blow molding (TForm®), sheet
forming, etc.
· Surface science: Surface reactivity, adhesive bonding, friction, lubrication, wear.
Thesis work description:
The numerical model developed in CEMEF will be improved regarding different orientations:
- the coupled staggered resolution at each time step of equations for mass and momentum conservation, in the solid and liquid regions,
- the use of calculated liquid and solid velocity fields in the equations for conservation of energy (heat transfer) and chemical species (solutes transport), in the context of a Eulerian-Lagrangian formulation (quasi Eulerian in liquid regions, Lagrangian in solid),
- the implementation of these equations in the existing level set formulation used to track the free surfaces,
- the accurate control of the existing procedures for adaptive and dynamic remeshing, which allow the optimisation of mesh local density and anisotropy, according to the different calculated
fields.
The PhD candidate will receive a formation and will develop his(her)
personal skills in the domain of numerical mechanics applied to fluids
and solids, insisting particularly on the fluid/structure interactions
aspects. Following this PhD work, he(she) will exploit and develop
his(her)capacities in R&D departments of different industries:
metallurgy, aeronautics, spatial, energy…
