The Rossiter modes of an open cavity were studied using bi-global linear analysis, local
instability analysis and nonlinear numerical simulations. Rossiter modes are normally seen …

We investigated the effects of two-dimensional sharp-edged rectangular bumps on Tollmien–
Schlichting (TS) wave evolution using direct numerical simulation. The bump height …

B layer flows over real surfaces are subject to the effects of its imperfections, which may
impact its stability and, therefore, the laminar to turbulent transition location. This has a large …

Global instability analysis of flows is often performed via time-stepping methods, based on
the Arnoldi algorithm. When setting up these methods, several computational parameters …

We test the linear stability of a compressible subsonic open cavity flow at various span-wise
wave-numbers, looking for both Rossiter and Görtler modes, also known as centrifugal …

The Rossiter modes of an open cavity were studied using global linear analysis and
nonlinear numerical simulations. The length over depth ratio was two and the Reynolds …

In practical scenarios, it is almost impossible to avoid the presence of surface irregularities.
Even for designs that avoid joints, gaps, and rivets, dirt may accumulate in operation. It is …

Triadic interactions are the fundamental mechanism of energy transfer in fluid flows and
arise due to the quadratic non-linearity of the Navier-Stokes equation. The bispectral mode …
