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…
Fluid-solid Floquet stability analysis of self-propelled heaving foils
Luis Benetti Ramos, Olivier Marquet, Michel Bergmann +1
We investigate the role of linear mechanisms in the emergence of nonlinear horizontal self-propelled states of a heaving foil in a quiescent fluid. Two states are analyzed: a perio…
Extended mean flow analysis of the circular cylinder flow
Olivier Marquet, Marco Carini
A new eigenvalue analysis is developed and applied to the circular cylinder laminar flow configuration to investigate the various mechanisms at play in the nonlinear saturation of…
Mean-flow Data Assimilation based on minimal correction of turbulence models: application to turbulent high-Reynolds number backward-facing step
Lucas Franceschini, Denis Sipp, Olivier Marquet
In this article, we provide a methodology to reconstruct high-Reynolds number turbulent mean-flows from few time-averaged measurements. A turbulent flow over a backward-facing step…
