Missions

The successful candidate will be required to digitally reproduce suspended thin film flows in the presence of surfactants (such as soap film). In particular, he/she will seek to determine the conditions necessary for destabilization by marginal regeneration between a film and a meniscus.

Activities

- Develop code based on the free software Basilisk to compute thin film flows in the presence of surfactants.
- Validate the results by comparing them with the solutions to the lubrication equations, solved using in-house code.
- Compare the numerical results obtained with existing experimental results.
- Write an article to present the results.

Skills

- Low Reynolds fluid mechanics and in the presence of free interfaces: expert
- Computational fluid dynamics. Use and development of open source codes such as Basilisk. Development of implicit finite difference codes: expert
- Written and oral scientific communication in English: proficient

Work Context

The successful candidate will work at the Rennes Institute of Physics, Beaulieu campus.
He/she will have access to a workstation and the IPR's digital cluster.
He/she will interact regularly with I. Cantat (Rennes University professor) to jointly define the stages of work and discuss results.
He/she will participate in scientific discussions within the “soap film” group of around five people (two researchers, two doctoral students, and several interns) and attend the scientific seminars of the Soft Matter team (around fifteen people).
