RESEARCH ACTIVITIES
High Performance Learning for Aeronautical Flow Physics
FUNDAMENTAL METHODS IN AI
Prospective works are carried out to apply AI techniques to propose, develop, or extent, AI methods in Deep Learning and Deep Reinforcement Learning.
Current Postdocs and PhDs :
Enrico Foglia : We study UQ estimation of deep learning models with collaboration with EPFL and mathematician at SUPAERO
Brice Martin & Laura Choquet : we investigate the partial observation problem, and its associated performance loss, in deep reinforcement problems.
Giovani Catalani : He explores potential amelioration of INR methods, in the scope or surrogate modeling in aerodynamics on large meshes.
Xintong Chen : She studies the fundamental problems of reproducibility and symmetry conservation in DL methods coupled to other non-linear systems.
ACCELERATING CFD SOLVERS
I currently lead research at DAEP to develop AI-based CFD solvers. Some part of the CFD solvers are replaced by a deep neural network. It contribute to the effort of improving the performance of CFD codes, especially on GPUs. This activity is realized in collaboration with AI experts (Jolibrain) and Cerfacs (Helios group : http://cerfacs.fr/helios/)
Current PhDs :
Xintong Chen : Investigating reproducibility and symmetry preservation of AI-based linear solver coupled to non-linear physics. The main focus is to accelerate using AI existing incompressible code that need to solve a linear Poisson equation.
AI FOR FLOW RECONSTRUCTION & IDENTIFICATION
Part of the AI activity is dedicated to flow reconstruction. In particular, denoising problems and missing data reconstruction are under investigation. First results on denoising and pressure reconstruction from PIV measurements show promising possibilities for deep learning to complement CFD and experiment in fluid mechanics. Part of the POLA3 project will investigate AI-based identification methods for non-linear systems
Current Postdocs :
Mateus Costa : He works on localizing acoustic sources in experiment by solving the inverse problem with AI techniques, in particular deep neural networks.
AI FOR OPTIMIZATION
Prospective works are carried out to apply AI techniques to develop new optimization procedures. This current work is sustained by 2 research master projects and a postdoc fellow funded by DGA (ETAP projet), in particular using Reinforcement Learning. Part of the DGA project POLA3 will also investigate optimization problems.
Current Postdocs and PhDs :
Enrico Foglia : He explores novel advanced geometric deep learning methods, like DiffusionNet, for surrogate modeling on Riemannian manifolds.
Brice Martin : Optimal unsteady aerodynamics by Artificial Intelligence
Felix Jose Zapata-Usandivaras : AI-based optimization of a rocket engine
Aeroacoustics
My research focuses on using high-fidelity simulations (Navier-Stokes CharlesX and LBM Palabos) to address aeroacoustics problems. Current investigations include :
- Characterizing high-fidelity codes with acoustic benchmarks and applications. Typical cases ongoing are a drone’s rotor as well as trailing edge noise of high-Re airfoils.
- Investigation of a jet-pump for propagation of acoustic waves in complex media, in collaboration with Stéphane Moreau from Sherbrooke Univ.
- Hydrodynamic-Acoustic coupling using forced LES simulations, with applications to cavity flows and vortex-sound.
Current PhD :
Andrea Arroyo : High-fidelity simulations (DNS), theory and machine learning for high speed trailing edge noise, in collaboration with Sherbrooke University
Tiphaine Arnould : High-fidelity simulations (high-order spectral LES) of realistic (high Reynolds numbers, turbulent) flows over a cavity. She investigates the sound production, and the fundamental coupling between cavity modes and Rossiter modes.
Bio-inspired aerodynamics
My research focuses on using high-fidelity simulations (Navier-Stokes CharlesX and LBM Palabos) to investigate bio-inspired flows. Three typical cases are studied currently :
- A boxfish, typical case of of high-efficient bluff body. This is investigated using LBM and experiment in collaboration with V. Chapin and E. Gowree
- A dragonfly wing with both corrugations and rear arc, showing overall good aerodynamic performance at low Reynolds number. Interesting complex flows emerged in this case, such as rapid transition to chaos.
- Flapping wing (insects, birds). Kinematics of flapping wings can be complex, especially since the associated flow is highly non-linear and unsteady. Finding methods to optimize these kinematics to extract maximum power in a highly efficient manner is challenging.
Current Postdocs and PhDs :
Brice Martin : Optimal unsteady aerodynamics by Artificial Intelligence
When Wei : Optimization of bio-inspired vehicles based on AI methods, simulations and experiments. Current work focuses on the boxfish species
