CERMICS - Fluid Dynamics Group
Research activities concern the mathematical modeling and numerical analysis in fluid and solid mechanics.
- compressible fluid/deformable solid interaction
- incompressible Navier-Stokes
- environmental flows (hydrology, porous media flows)
- aeroacoustics
Various numerical methods are
developed and analyzed
- hybrid high-order methods (HHO), discontinuous Galerkin (DG)
- a posteriori error analysis, adaptivity
- immersed boundary methods
- reduced basis methods
Left: acoustic scattering around an ellipsoid;
Right: shock wave interacting with a circular fragmenting shell
