Active control of laminar boundary layers with dielectric barrier discharge (DBD) plasma
actuators (PAs) has made considerable progress in the last 15 years. First pioneering …

THE field of fluid mechanics involves a range of rich and vibrant problems with complex
dynamics stemming from instabilities, nonlinearities, and turbulence. The analysis of these …

This review article is concerned with the design of linear reduced-order models and control
laws for closed-loop control of instabilities in transitional flows. For oscillator flows, such as …

We extend the resolvent-based estimation approach recently introduced by Towne etal.(J.
Fluid Mech., vol. 883, 2020, A17) to obtain optimal, non-causal estimates of time-varying …

Transonic buffet is a phenomenon of aerodynamic instability with shock wave motions which
occurs at certain combinations of Mach number and mean angle of attack, and which limits …

In this work we perform reactive control of stochastic disturbances in forced turbulent jets
based on destructive interference. The study is motivated by the success of recent studies in …

This work develops a reduced-order model-based feedback control strategy for suppressing
vortex-induced vibration (VIV) of a spring-mounted cylinder. First, a reduced-order model …

Obtaining low-order models for unstable flows in a systematic and computationally tractable
manner has been a long-standing challenge. In this study, we show that the Eigensystem …

Three methods are considered for estimating the downstream evolution of wavepackets in
turbulent jets based on upstream measurements. The parabolised stability equations are …

In this study the parabolized stability equations (PSE) are used to build reduced-order-
models (ROMs) given in terms of frequency and time-domain transfer functions (TFs) for …
