The modelling of multi-phase and multi-fluid flows remains a key challenge in both academia (astrophysics, geophysics, meteorology, etc.) and industry (combustion, nuclear, health, etc.) due to the complexity of dispersed phases and their interactions. The “backbone” multi-fluid model, based on Euler-like equations for mass, momentum, and energy, provides a simpli- fied framework that can be discretized numerically using the recently developed Geometry, Energy, and Entropy Compatible (GEEC) approach. This internship will be dedicated to extending the GEEC methodology to multi-fluid applications through systematic numerical validation on 1D and 2D academic test cases.

THE CANDIDATE

You are a final year Ecole d’Ingénieur or Master 2 student specializing in fluid mechanics, numerical simulations, or applied mathematics. Knowledge of multi-phase flows is a plus. The candidate must have experience or interest in programming, particularly C++, and basic knowledge of parallelisation paradigms is welcome. Excellent English communication skills, both spoken and written, are required.

Your CV, cover letter, and grades for the last two years are to be sent to:
pierre.boivin@univ-amu.fr
ksenia.kozhanova@univ-amu.fr
