Interview with CoEC partner Vincent Moureau

 

Vincent Moureau is a CoEC team leader and CNRS (French National Center for Scientific Research) senior researcher at CORIA (Complexe de Recherche Interprofessionnel en Aérothermochimie). His research is focused on turbulent combustion and spray modelling, and on the development of the YALES2 solver for Large-Eddy Simulation and Direct Numerical Simulation of turbulent flows in complex geometries using massively parallel computers. This flow solver is now used by a large community of researchers and engineers for various applications such as aeronautics and space, renewable energies, bio-mechanics, process engineering. He received the Yves Chauvin award for his PhD thesis in 2005, the 3rd prize of the Bull Joseph Fourier award for the promotion of numerical simulation in 2010, an IBM faculty award in 2011, and the aeronautical and aerospace science award of the French Academy of Science in 2018.

When you work for cleaner air on the planet, the feeling is like being at the right place. Computational Fluid Dynamics is an incredible tool for understanding complex physics                         and helping to design cleaner engines.

Vincent Moureau

What are your team’s main tasks in the CoEC project?

 

The CNRS-CORIA team works mainly on developing new scalable algorithms for spray combustion, which is found at the core of aeronautical engines. More specifically, we aim at introducing more adaptivity to our simulations. During a simulation, the mesh changes and the grid partitioning evolves in order to have performances always close to ideal.

 

What stage of implementation are you at?

 

We have made very good progress on dynamic load-balancing for Euler/Lagrange models, concluded with the submission of a paper. We are still working on error estimators for spray flames to drive the mesh adaptation and on the optimization of the dynamic adaptation algorithms.

 

What are the main challenges? Which part of the project do you think will be the most difficult?

 

The most difficult part is to deal with very dynamical phenomena such as those encountered in spray flames and liquid fuel atomization. It requires to deal with heavy meshes with several hundreds of million cells or beyond one billion cells.

 

Are you satisfied or maybe inspired by the fact that this project can solve many important problems related to air pollution and climate change?

 

Definitely. Computational Fluid Dynamics is an incredible tool for understanding complex physics and help designing cleaner engines but we can still improve CFD tools to be even more disruptive.

 

How does it feel when you work with this project for cleaner air on the planet?

 

It feels like being at the right place to make a difference.

 

What would you be if you were not a researcher?

 

I would probably be a combustion engineer in the aeronautical industry to design cleaner engines.

 

Many young people find science difficult. What would you tell them? What advice do you have for young people who want to follow in your footsteps?

 

Science and research, in general, are difficult but contributing to solve important societal problems is highly motivating and young people with new and disruptive ideas are needed.

 

What do you dream about?

 

That my kids and the new generation keep hope in the future and find solutions to all the upcoming societal challenges.
