Présentation

FIELDS OF EXPERTISE:

· Developing efficient numerical methods: the objective is to increase the capabilities of the numerical simulations by developing more accurate, reliable, and efficient computational methods. The central subjects deal with the development of high order numerical schemes with high fidelity shock capturing features, sub-grid scale modeling in Large Eddy Simulation (LES), multiresolution procedures based on a posteriori error estimate for adaptive mesh refinement and the processing of unsteady boundary conditions. These methods have recently been coupled with a new resolution strategy based on time operator splitting in the context of very localized and stiff reaction fronts for combustion problem.

· Simulating fluid–structure interactions for transient dynamics problems, such as the impact of shock waves onto a structure, with possible fracturing causing the ultimate breakdown of the structure. We developed a new coupling algorithm between a compressible fluid flow and a moving body using an Embedded Boundary method that ensures the conservation of fluid mass and the balance of momentum and energy between fluid and solid.

· Flow analysis and reduction of the dynamics: we developed techniques for the generation of data on a subset of the domain that capture the relevant spatio-temporal features of the flow. These techniques were manly used to generate unsteady inlet boundary conditions and wall modeling techniques for zonal approach in LES. They were based on modal decompositions (i.e. POD, DMD) and derivation of low order dynamical systems.

· Manipulation and fluid flow control: a response surface-based optimizer was used to find the best set of Vortex Generator parameters to control the adverse pressure gradient at the rear-end of a car to achieve significant drag reduction.
