Absolute/Convective Instabilities and Spatial Growth in a Vortex Pair,y enforced between take-offs and landings. This spacing limits the maximum take-o. and landing frequency in saturated airports [.]. A number of studies have been devoted to the understanding of vortex wake dynamics,usually modeled by a pair of counterrotating vortices. Two types of vortex pair three

Ultrasound Scattering by Forced Laminar Wakes,low boundaries of the observation domain continuously. It is the case of boundary layers [.],jets [.,.] and notably wakes [.]..Actually,concepts of absolute and convective instability have proved to be useful to classify the different types of open flows according to their local dynamic behavior. A

A Numerical Study of the Elliptic Instability of a Vortex Pair, is studied by direct numerical simulations. The computations allows the prediction of both the linear regime of the instability development and the non-linear regime including the transition to a locally turbulent flow.

On the Stability of Vortices in an Ideal Gas,ined with the geometrical optics (WKB) stability theory which consists in studying the evolution of short-wavelength disturbances localized along the trajectories of the vortex. The first one corresponds to parametric resonances arising when a vortex is periodically compressed; the resulting instabi

Three-Dimensional Instabilities of a Counterrotating Vortex Pair, interest in this flow is,to a great extent,due to its relevance to the problem of aircraft trailing wakes. In addition,the counterrotating vortex pair represents one of the simplest flow configurations for the study of elementary vortex interactions, which can yield useful information for the under
