Abstract Backward-Facing Step (BFS) flow is one representative model for separation flows,
which can be widely seen in aerodynamic flows (airfoil, spoiler, high attack angle process) …

This article reviews linear instability analysis of flows over or through complex two-
dimensional (2D) and 3D geometries. In the three decades since it first appeared in the …

A summary is presented of physical insights gained into three-dimensional linear instability
through solution of the two-dimensional partial-differential-equation-based nonsymmetric …

Numerical simulations are used to investigate the resonant instabilities in two-dimensional
flow past an open cavity. The compressible Navier–Stokes equations are solved directly (no …

This paper is concerned with the behavior of flows over a backward-facing step geometry for
various expansion ratios H/h= 1.9423, 2.5 and 3.0. A literature survey was carried out and it …

Thermoacoustic combustion instability is one of the most challenging operational issues in
several high-performance, low-emissions combustion technologies, including gas turbines …

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 …

Numerical solutions of 2-D laminar flow over a backward-facing step at high Reynolds
numbers are presented. The governing 2-D steady incompressible Navier–Stokes equations …

The control of separated fluid flow by reduced-order models is studied using the two-
dimensional incompressible flow over an open square cavity at Reynolds numbers where …

A linear stability analysis shows that the jet in crossflow is characterized by self-sustained
global oscillations for a jet-to-crossflow velocity ratio of 3. A fully three-dimensional unstable …
