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 …

THERE is good reason for optimism regarding the future of global linear instability and a
certain degree of euphoria surrounding its recent success [1, 2], three decades after the first …

The low-frequency unsteadiness in the direct numerical simulation of a Mach 2.9 shock
wave/turbulent boundary layer interaction with mean flow separation is analysed using …

The role of free-stream turbulence (FST) in the hydrodynamic instability mechanisms and
transition to turbulence in laminar separation bubbles (LSBs) was investigated using direct …

The convective primary amplification of a forced two-dimensional perturbation initiates the
formation of essentially two-dimensional large-scale vortices in a laminar separation bubble …

We investigate flow instability created by an oblique shock wave impinging on a Mach 5.92
laminar boundary layer at a transitional Reynolds number. The adverse pressure gradient of …

Resolvent analysis is used to study the low-frequency behaviour of the laminar oblique
shock wave/boundary layer interaction (SWBLI). It is shown that the computed optimal gain …

Experiments were conducted to study the transition and flow development in a laminar
separation bubble (LSB) formed on an aerofoil. The effects of a wide range of free-stream …

Two-and three-dimensional modal and non-modal instability mechanisms of steady
spanwise-homogeneous laminar separated flow over airfoil profiles, placed at large angles …

This paper examines the three-dimensional cellular patterns appearing on wings in
subsonic stall and transonic buffet conditions. Unsteady Reynolds-averaged Navier–Stokes …
