Full waveform inversion using triangular waveform adapted meshes
Keith J. Roberts, Alexandre Olender, Lucas Franceschini +3
In this article, continuous Galerkin finite elements are applied to perform full waveform inversion (FWI) for seismic velocity model building. A time-domain FWI approach is detaile…
Mean- and unsteady-flow reconstruction with one or two time-resolved measurements
Lucas Franceschini, Denis Sipp, Olivier Marquet
In this article, we propose a methodology to reconstruct, in a single step, the mean- and unsteady properties of a flow from very few time-resolved measurements. The procedure is b…
Identification and reconstruction of high-frequency broadband fluctuations in a turbulent flow exhibiting low-frequency deterministic motions
Lucas Franceschini, Denis Sipp, Olivier Marquet +2
The turbulent flow around a squared-section cylinder at exhibits both a low-frequency Vortex-Shedding (VS), a common feature of all bluff-body flows, and high-frequency…
