Erwan Liberge

Erwan Liberge is a teacher-researcher at the University of La Rochelle, France, specializing in computational methods for fluid-structure interaction (FSI) problems. He is affiliated with the M2N team (E1-M2N) within the CNU 60 research section and works under the CNRS INSIS department. His academic rank aligns with Associate Professor in the French system.

His research focuses on numerical modeling in fluid mechanics and structural mechanics, utilizing the Lattice Boltzmann Method (LBM) and Proper Orthogonal Decomposition (POD) for model reduction. Key applications include turbulence modeling, flow-induced vibrations in cylinder arrays, and infiltration heat recovery in buildings. He has developed GPU-accelerated solvers for 3D flows in porous materials and explored penalty/duality methods in FSI.

The 15 most recent publications (2014–2023) reflect a consistent emphasis on POD-based reduced order modeling (for incompressible flows, rotating solids, and parametric variations) and LBM with volume penalization for obstacle flow simulation. These works intersect computational fluid dynamics, solid mechanics, and numerical mathematics, often addressing coupled systems and nonlinear stability.

Erwan collaborates with researchers like Aziz Hamdouni, Claudine Béghein, and Antoine Falaize. He has presented at international conferences (ICMMES, ECCOMAS, ASME) and contributed to journals such as Journal of Fluids and Structures and Physical Review E. His team (E1-M2N) focuses on mathematical modeling and simulation for industrial applications.
