We develop a method to estimate space–time flow statistics from a limited set of known data.
While previous work has focused on modelling spatial or temporal statistics independently …

Resolvent analysis is a powerful tool that can reveal the linear amplification mechanisms
between the forcing inputs and the response outputs about a base flow. These mechanisms …

Self-excited vibrations represent a big concern in engineering, particularly in automotive,
railway and aeronautic industry. Many lumped models have been proposed over the years …

The flows around a NACA 0018 airfoil at a chord-based Reynolds number of case behaves
more like an amplifier and its nonlinear forcing is far less structured. The two cases suggest …

Transonic buffet is commonly associated with self-sustained flow unsteadiness involving
shock-wave/boundary-layer interaction over airfoils and wings. The phenomenon has been …

Resolvent analysis is a powerful tool for studying coherent structures in turbulent flows.
However, its application beyond canonical flows with symmetries that can be used to …

Shock waves interacting with turbulent boundary layers on wings can result first in self-
sustained flow unsteadiness and eventually in structural vibration. Due to its importance to …

This article presents a reconstruction of the unsteady behaviour of a round jet at a Reynolds
number equal to 3300, from the sole knowledge of the time-averaged flow field and one …

A methodology is presented that exploits both data-assimilation techniques and resolvent
analysis for reconstructing turbulent flows, containing organized structures, with an efficient …

We analyze the resolvent operator in three flows around a nominal NACA-0012 airfoil at Re
C= 50, 000 and 5∘ angle of attack. In particular, we study two naturally develo** flows …
