Coherent interferometric imaging in a random flow
Etienne Gay, Luc Bonnet, Christophe Peyret +2
This paper is concerned with the development of imaging methods to localize sources or reflectors in inhomogeneous moving media with acoustic waves that have travelled through them…
Adaptive reconstruction of imperfectly-observed monotone functions, with applications to uncertainty quantification
L. Bonnet, J. -L. Akian, É. Savin +1
Motivated by the desire to numerically calculate rigorous upper and lower bounds on deviation probabilities over large classes of probability distributions, we present an adaptive…
Multiscale analysis of spectral broadening of acoustic waves by a turbulent shear layer
Josselin Garnier, Etienne Gay, Éric Savin
We consider the scattering of acoustic waves emitted by an active source above a plane turbulent shear layer. The layer is modeled by a moving random medium with small spatial and…
Kinetic modeling of multiple scattering of acoustic waves in randomly heterogeneous flows
Jean-Luc Akian, Éric Savin
We study the propagation of sound waves in a three-dimensional, infinite ambient flow with weak random fluctuations of the mean particle velocity and speed of sound. We more partic…
Computation of Higher-Order Moments of Generalized Polynomial Chaos Expansions
Éric Savin, Béatrice Faverjon
Because of the complexity of fluid flow solvers, non-intrusive uncertainty quantification techniques have been developed in aerodynamic simulations in order to compute the quantiti…
Sparse polynomial surrogates for aerodynamic computations with random inputs
Eric Savin, Andrea Resmini, Jacques Peter
This paper deals with some of the methodologies used to construct polynomial surrogate models based on generalized polynomial chaos (gPC) expansions for applications to uncertainty…
Kinetic modeling of multiple scattering of elastic waves in heterogeneous anisotropic media
Ibrahim Baydoun, Éric Savin, Régis Cottereau +2
In this paper we develop a multiple scattering model for elastic waves in random anisotropic media. It relies on a kinetic approach of wave propagation phenomena pertaining to the…
