Optimal spanwise-periodic control for recirculation length in a backward-facing step flow
E. Yim, I. Shukla, F. Gallaire +1
Three-dimensional control is considered in the flow past a backward-facing step (BFS). The BFS flow at Reynolds number (defined with the step height and the maximum inlet…
Stochastic modelling of a freely rotating disk facing a uniform flow
E. Boujo, O. Cadot
The fluid-structure interaction between a thin circular disk and its turbulent wake is investigated experimentally and described with a low-order stochastic model. The disk faces a…
Pancake making and surface coating: optimal control of a gravity-driven liquid film
E. Boujo, M. Sellier
This paper investigates the flow of a solidifying liquid film on a solid surface subject to a complex kinematics, a process relevant to pancake making and surface coating. The flow…
Second-order sensitivity in the cylinder wake: optimal spanwise-periodic wall actuation and wall deformation
E. Boujo, A. Fani, F. Gallaire
Two-dimensional (2D) flows are efficiently controlled with spanwise waviness, i.e. spanwise-periodic (SP) wall blowing/suction/deformation. We tackle the global linear stability of…
Processing time-series of randomly forced self-oscillators: the example of beer bottle whistling
E. Boujo, C. Bourquard, Y. Xiong +1
We present a model-based, output-only parameter identification method for self-sustained oscillators forced by dynamic noise, which we illustrate experimentally with an aeroacousti…
Output-only parameter identification of a colored-noise-driven Van der Pol oscillator -- Thermoacoustic instabilities as an example
Giacomo Bonciolini, Edouard Boujo, Nicolas Noiray
The problem of output-only parameter identification for nonlinear oscillators forced by colored noise is considered. In this context, it is often assumed that the forcing noise is…
