The objective of this article is to review some developments in the use of adjoint equations in
hydrodynamic stability theory. Adjoint-based sensitivity analysis finds both analytical and …

This review article addresses the dynamics and control of low-frequency unsteadiness, as
observed in some aerodynamic applications. It presents a coherent and rigorous linearized …

The two-dimensional flow around a rotating circular cylinder is studied at Re= 100. The
instability mechanisms for the first and second shedding modes are analysed. The region in …

In a thermoacoustic system, such as a flame in a combustor, heat release oscillations couple
with acoustic pressure oscillations. If the heat release is sufficiently in phase with the …

The sensitivity of the flow around three-dimensional blunt geometry is investigated
experimentally at Reynolds number. Vertical and horizontal control cylinders are used to …

Many fluid flows, such as bluff body wakes, exhibit stable self-sustained oscillations for a
wide range of parameters. Here we study the effect of weak noise on such flows. In the …

In this work the flip–flop instability occurring in the flow past two side-by-side circular
cylinders is numerically investigated within the range of non-dimensional gap spacing. The …

The sensitivity of the global properties of a two-dimensional turbulent wake produced by the
separated flow of a 'D'-shaped cylinder at is investigated experimentally using a small …

Wind tunnel tests were conducted to investigate the effect of the self-issuing jet flow control
on the vortex-induced vibrations (VIVs) of a streamline single-box girder at various angles of …

The sensitivity to steady local disturbances of the turbulent wake over a 3D blunt body with
an axisymmetric trailing edge is investigated at Re= 2.1× 10 4. The flow presents a favored …
