Description du sujet

Context:

The macroscopic modeling of the blast effects of aluminized explosives is currently treated with empirical models. These models lead to perfectible results. Improvements would require the introduction of identified physics at the mesoscopic scale. Initial work, carried out as part of a thesis, is underway in this area using LES (Large Eddy Simulation) of flows representative of that generated by the detonation of an explosive. The results obtained today show a need to progress in the modeling of aluminum combustion under conditions as close as possible to those encountered after the detonation of a solid explosive.

Objectives:

The proposed work is part of this process of progress in the modeling of aluminum combustion. More specifically, it relates to the design and implementation of elementary experiments. Another PhD Thesis, proposed in parallel, is related to the modeling and numerical simulation aspect of the experiments (performed in IMFT). The ultimate goal is to feed the macroscopic models of blast effects of aluminized explosives.

Profil du candidat

The candidate must have a Master degree in Mechanical or Chemical engineering.

The post requires a high level of communication skills, both oral and written (French or English required) to be able to present at conferences and write articles in scientific publications, and sound knowledge of data processing.

We are looking for a PhD fellow who will be able to become fully involved with the project, with a thirst for knowledge, a certain independence of thought and strong motivation to develop skills in the field of energy and propulsion. In addition, the candidate must be able to work in a team on multi-disciplinary projects.
