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…
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…
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…
