INTERNSHIP MASTER : Modeling particle transport within a thin liquid film – 6 months

JOB ENVIRONMENT:

Institut Mines-Télécom is the leading public group of engineering and management Grandes Écoles in France. Consisting of eight public graduate Grandes Écoles and two subsidiary graduate schools, Institut Mines-Télécom leads and develops a rich ecosystem of partner schools, economic, academic and institutional partners, key players in education, research and economic development.

Mines Saint-Étienne, a graduate school of the Institut Mines-Télécom, is responsible for education, research, innovation, industrial transfer and scientific culture dissemination. With 2,500 students, 500 staff and a budget of €50m, it has 3 campuses dedicated to the industry of the future, health and well-being, and digital sovereignty and microelectronics. It is ranked in the top 15 graduate engineering schools in France and the top 500 universities worldwide.

The 2023-2027 strategy of Mines Saint-Etienne is in line with that of Institut Mines Telecom. It aims to:

• · Support the ecological, digital and generational transitions and educate the people involved
• · Support national and European sovereignty in microelectronics and digital technology

To support this strategy, it is recruiting a 6-month internship student in fluid mechanics

JOB DESCRIPTION:

Presentation of internship assignments and activities : Particle transport within liquid films is encountered in several scenarios, such as biological and environmental flows, and in chemical and pharmaceutical engineering applications. In those flows, hydrodynamics and particle interact. Modeling the particle transport and in particular the interplay between hydrodynamics and particle flows (hydrodynamics influences particles and vice-versa) is extremely challenging and requires a high computational cost. To tackle this problem, in this project we aim at modeling the film flow with a low-dimensional shallow-water formulation (integration of the Navier-Stokes equations over the film thickness), and the particle transport with a DEM approach (discrete element method). The scientific challenge consists in coupling these two approaches (shallow-water with DEM). For this, a Matlab in-house flow solver will be employed. Firstly, the liquid film will be interacting with fixed particles, then the particles will be allowed to move according to the hydrodynamics of the film.

Keywords : fluid dynamics, particle transport, computational analysis, thin films.

The internship is based on the Saint-Étienne campus.
