Adjoint-based linear sensitivity of a hypersonic boundary layer to steady wall blowing-suction/heating-cooling
Arthur Poulain, Cédric Content, Georgios Rigas +2
For a Mach 4.5 flat-plate adiabatic boundary layer, we study the sensitivity of the first, second Mack modes and streaks to steady wall-normal blowing/suction and wall heat flux. T…
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…
Interpolatory-based data-driven pulsed fluidic actuator control design and experimental validation
Charles Poussot-Vassal, Pauline Kergus, Franck Kerhervé +2
Pulsed fluidic actuators play a central role in the fluid flow experimental control strategy to achieve better performances of aeronautic devices. In this paper, we demonstrate, th…
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…
Non-linear input/output analysis: application to boundary layer transition
Georgios Rigas, Denis Sipp, Tim Colonius
We extend linear input/output (resolvent) analysis to take into account nonlinear triadic interactions by considering a finite number of harmonics in the frequency domain using the…
