معرفی
Remi Chassagne is a Research Fellow at Grenoble Alpes University, affiliated with the Laboratory of Geophysical and Industrial Flows (LEGI), a joint research unit of CNRS, Grenoble INP, and Grenoble Alpes University, where he contributes to the MEIGE team.
His research focuses on:
- Sediment Transport mechanics using mechanistic and granular approaches
- Vertical grain size segregation and diffusion remixing in sediment beds
- Eulerian-Eulerian two-phase flow modeling (SedFoam)
- Bridging particle-scale phenomena to continuum models
- Interactions between sediment particles of different sizes
Chassagne's work integrates discrete element modeling (DEM) for particle-scale dynamics with continuum modeling to address sediment transport in geophysical contexts. His research emphasizes vertical grain size segregation, infiltration dynamics of small grains in coarse beds, and the development of numerical frameworks like SedFoam for multiphase flow simulation. This mechanistic approach connects micro-scale particle interactions to macro-scale sediment transport predictions.
Analysis of his publication record (2016-2024) reveals consistent focus on sediment transport mechanics, with dominant themes in granular flow behavior, size segregation processes, and computational modeling advancements. Key contributions include frictional-collisional bedload models, sediment-vegetation interactions, and bi-disperse mixture mobility. His work demonstrates strong integration of computational methods with experimental validation through LEGI's hydrodynamic facilities.
As part of LEGI's MEIGE team, Chassagne utilizes the laboratory's advanced infrastructure including hydrodynamic tunnels, wave channels, and rotating platforms to investigate geophysical flows relevant to river, coastal, and industrial applications.
