▪ Abstract In this review we describe the discovery and development of understanding of the
so-called elliptical instability. This is the name given to the linear instability mechanism that …

Experimental studies dealing with the wake of isolated stationary bluff bodies are reviewed.
After briefly recalling the pioneering works in this domain, the paper focuses on recent …

Direct numerical simulations (DNS) of laminar separation bubbles on a NACA-0012 airfoil at
Rec= 5× 104 and incidence 5° are presented. Initially volume forcing is introduced in order …

This paper presents three-dimensional (3D) direct numerical simulations (DNS) of flow past
a circular cylinder over a range of Reynolds number (, where the weakest flow three …

Flow (of a Newtonian and incompressible fluid) separation around a square cylinder for
Reynolds numbers (Re) in the range of 10–400 is investigated through direct numerical …

This article deals with the interaction of co-rotating vortices, in configurations similar to those
found in the extended near-wake of typical transport aircraft. The fundamental process of …

Direct stability analysis and numerical simulations have been employed to identify and
characterize secondary instabilities in the wake of the flow around two identical circular …

The turbulent flows and tangled magnetic fields of the Earth's plasma sheet are explored
theoretically and by means of ISEE‐2 plasma and magnetic‐field measurements. The goal …

Instantaneous and time-averaged flow separation locations for the canonical case of flow
past a circular cylinder are investigated through direct numerical simulations. It is found that …

Flow transitions are an important fluid-dynamic phenomena for many reasons, including the
direct effect on the aerodynamic forces acting on the body. In the present study, two …
