Vorticity-dependent and symmetry-preserving LES models
Oscar Cosserat, Dina Razafindralandy, Can Selçuk
Within the Large Eddy Simulation framework, we propose a methodology based on the Lie theory to derive symmetry-preserving turbulence models. We apply this methodology to the incom…
Hydrogen uptake kinetics of cathodic polarized metals in aqueous electrolytes
L. Cupertino-Malheiros, M. Duportal, T. Hageman +1
We use a unique combination of electrochemical techniques to elucidate the dependency of hydrogen evolution reaction (HER) and absorption on pH and overpotential for iron and nicke…
Normal forms of -graded -manifolds
Alexei Kotov, Camille Laurent-Gengoux, Vladimir Salnikov
Following recent results of A.K. and V.S. on -graded manifolds, we give several local and global normal forms results for -structures on those, i.e. for differential…
Data-Driven Key Performance Indicators and Datasets for Building Energy Flexibility: A Review and Perspectives
H. Li, H. Johra, F. de Andrade Pereira +15
Energy flexibility, through short-term demand-side management (DSM) and energy storage technologies, is now seen as a major key to balancing the fluctuating supply in different ene…
Error analysis of a residual-based stabilization-motivated POD-ROM for incompressible flows
Tomás Chacón Rebollo, Samuele Rubino, Mourad Oulghelou +1
This article presents error bounds for a velocity-pressure segregated POD reduced order model discretization of the Navier-Stokes equations. The stability is proven in L infinity (…

Alexei Kotov, Vladimir Salnikov
In this paper we address several algebraic constructions in the context of groupoids, algebroids and -graded manifolds. We generalize the results of integration of $\mat…
Surface transfer coefficients estimation for heat conduction problem using the Bayesian framework
Julien Berger, Clemence Legros
This work deals with an inverse two-dimensional nonlinear heat conduction problem to determine the top and lateral surface transfer coefficients. For this, the \textsc{B}ayesian fr…
Assessing the wall energy efficiency design under climate change using POD reduced order model
Julien Berger, Cyrille Allery, Anaïs Machard
Within the environmental context, numerical modeling is a promising approach to assessing the energy efficiency of buildings. Resilient buildings need to be designed, and capable o…
Symplectic Groupoids for Poisson Integrators
Oscar Cosserat
We use local symplectic Lie groupoids to construct Poisson integrators for generic Poisson structures. More precisely, recursively obtained solutions of a Hamilton-Jacobi-like equa…
Estimation of the thermal properties of an historic building wall by combining Modal Identification Method and Optimal Experiment Design
Julien Berger, Benjamin Kadoch
The estimation of wall thermal properties by \emph{in situ} measurement enables to increase the reliability of the model predictions for building energy efficiency. Nevertheless, r…
