Although the stability properties of the wake past impervious bluff bodies have been widely
examined in the literature, similar analyses regarding the flow around and through porous …

The synchronization process between the fuel-feeding excitation (ff) and the local
equivalence ratio (ϕ local) is a key issue that has not been well studied numerically under …

The present paper describes a microfluidic oscillator based on facing impinging jets and
operating in laminar flow conditions. Using appropriate microchannel configurations …

The experimental and numerical investigation presented by Bertsch et al.(Phys. Rev. Fluids,
vol. 5, 2020a, p. 054202) describes the self-sustained oscillations induced by the interaction …

A counterintuitive destabilizing effect of the surface tension in planar wakes has been
observed by Tammisola et al.[“Effect of surface tension on global modes of confined wake …

In this paper, the possibility of absolute instability in a plane unidirectional jet is analysed.
We consider a parametrized family of velocity profiles with variable inflection point location …

The spatio-temporal development of an incompressible two-dimensional viscous wake flow
confined by two flat slipping plates is investigated by means of direct numerical simulation …

The precessing vortex core (PVC) and symmetric coherent structures in partly confined
swirling flows of gas turbine combustors are investigated numerically. The computational …

The instability of the Kármán vortex street is revisited under a spatio-temporal perspective
that allows the taking into account of the advection of the vortices by the external flow. We …

We have investigated the stability of a double vortex street, induced in a rectangular
container by a tape, or a rope, moving at high speed on its free surface. Depending on the …
