We continue our seminar series on Thursday, Oct. 24th at 13.00
On site: Salón de Grados (Leganés)
For this event in the Aerospace PhD Seminar Series, we had the pleasure of hosting Dr. Julien Favier, Professor in Fluid Mechanics at Aix Marseille University.
The event took place in the Salón de Grados on Thursday, October 24th at 13:00 pm and was streamed (Online).
Julien Favier is Professor in Fluid Mechanics at Aix Marseille University, expert in numerical modeling of fluid-structure interactions applied to aeronautical and biological flows. After a PhD in Toulouse on flow control in aeronautics using wind tunnel experiments and POD reduced order modeling, he moved as a postdoc to Genova for 4 years where he specialized in Immersed Boundary methods, and then 4 years in Madrid at CIEMAT where he refined his expertise in moving /deformable structures structures immersed in fluid flows. After short periods of visiting researcher at Queens University in Kingston, Canada and in Manchester, UK, he joined Aix Marseille Unviersity as Assistant Prof in 2012, at the M2P2 laboratory. In 2015, he took the lead of the ITC team (instabilities, Turbulence, Control) composed of 10 permanent reserachers for 8 years, and he is now director of the M2P2 lab since january 2013 (110 personnel including 40 permanent researchers). Since january 2024, he is coordinator of the EU project FALCON on fluid-structure intreraction in aeronautics involving major academic and industrial partners over 6 countries in Europe.
“Fluid-Structure interactions in aeronautics using lattice Boltzmann method”
Abstract:
In this talk I will present recent numerical developments on the simulation of fluid-structure interaction (FSI) phenomena using the lattice Boltzmann method, which has gained a rapid sucess over the past 15 years for modeling subsonic flows in the quasi-incompressible regime, thanks to its low-dissipative schemes, computational efficiency, and good parallelization properties. Its cartesian nature, fitting very well with immersed boundary method (IBM), makes it naturally very efficient for the simulation of FSI phenomenon.
Although FSI solvers based on coupling LBM and IBM to finite element solvers have been applied to a large spectrum of applications (biomedical, chemical engineering, etc.), tackling realistic conditions for FSI in aeronautics still remains a challenge nowadays: large deformations and high frequency vibrations of structures immersed in high-Re and high-Ma flows. The presence of turbulent boundary layers and discontinuities in supersonic regimes significantly complicates the mathematical formulation, as well as their numerical implementation.
The presentation will focus on specific IBM-based methods developed at M2P2 laboratory (Aix-Marseille University), able to ensure conservativity in the discrete sense in realistic conditions. To preserve CPU times and reach solutions in reasonable times, explicit partitioned approaches will be preferred over monolithic solvers, and specific IBM-based methods will be presented, illustrated by recent results obtained with the LBM solver ProLB.
The seminar begin at 13:00 pm and will take place in the Salón de Grados, Leganés.
