The objective of the postdoc project is to analyze turbulence-particle and particle-particle interactions and their potential coupling in intense sediment transport regime (sheet-flow) using a two-phase flow modeling approach. This work will be done using new laboratory open-channel flow experiments performed at LEGI (H. Guta PhD) in order to better understand these fine-scale processes.


The recruited candidate will be in charge of performing turbulence-resolving (Large Eddy Simulation) and turbulence-averaged (RANS) two-phase flow simulations using the open-source model SedFoam to reproduce and interpret measurement results from the experiments. The objective of the postdoc is to analyze in-depth the relative contributions of turbulent and granular stresses and the turbulent kinetic energy budgets of the fluid and granular phases. Ultimately, the goal is to improve the constitutive relationships for two-phase flow models of sediment transport.


• PhD in multi-phase flows, granular flows or turbulence modeling.
• Experience in using Linux environment and HPC facilities.
• Programming skills (python, C / C ++).
• Strong scientific writing skills are mandatory.

Work Context

The Laboratory of Geophysical and Industrial Flows (LEGI) is a public research laboratory of the COMUE University of Grenoble Alpes. It is a joint research unit (UMR 5519) common to the National Center for Scientific Research ([CNRS]), Université Grenoble Alpes (UGA) and Institut Polytechnique de Grenoble (Grenoble INP), which gathers more than 150 people, including 60 permanent and as many PhD students and postdocs.
Research activities in Fluid Mechanics and Transfer conducted at LEGI combine modeling, testing (more than 40 experimental facilities including large equipment), high performance numerical simulation (parallel computers, national computing centers ...) and the development of innovative flow measuring systems. These activities are related to numerous fields of application within environmental as well as industrial issues.
The successful candidate will work in the MEIGE team, Modeling, Experiments and Instrumentation for Geophysics and the Environment, gather all LEGI's research activities related to flows in natural environments: ocean, atmosphere, coastline. The research conducted within the team focuses on describing, understanding and modeling the dynamics of these environments at small scales. This approach combines physical modeling approaches in the laboratory, in-situ measurement campaigns and theoretical and numerical modeling approaches. The research activities of the team can be grouped according to three main themes (http://www.legi.cnrs.fr/web/spip.php?rubrique188&lang=fr: :
- Boundary Layer processes and turbulence in geophysics
- Gravity waves : internal and surface waves
- Environnemental engineering.
