Computational approaches are being developed to study a range of problems in
aeroacoustics. These aeroacoustic problems may be classified based on the physical …

An overview of jet noise research is presented wherein the principal movements in the field
are traced since its beginnings. Particular attention is paid to the evolution of our …

Reconnections of coherent filamentary structures play a key role in the dynamics of fluids,
redistributing energy and helicity among the length scales, triggering dissipative effects, and …

A global stability analysis of Kelvin's vortex ring to three-dimensional disturbances of
infinitesimal amplitude is made. The basic state is a steady asymptotic solution of the Euler …

The linear stability of the axisymmetric flow past a fixed-shape spheroid with free-slip
boundary conditions is studied numerically to gain some insight into the path instability of …

The state of the art in describing the eigen-oscillations of a vortex ring in an ideal
incompressible fluid is reviewed. To describe eigen-oscillations, the displacement field is …

We revisit the Moore–Saffman–Tsai–Widnall instability, a parametric resonance between left-
and right-handed bending waves of infinitesimal amplitude, on the Rankine vortex strained …

Вихревое кольцо является хорошо известным и очень популярным объектом динамики
жидкости. Его исследования тянутся с прошлого века, когда кольцевой вихрь …

The main goal of the paper is to assess the contribution of large-scale vortices to the noise of
the subsonic turbulent jet (M= 0.35, Re= 3.2· 105) in the selected frequency bands (Sh∼ 0.2 …

The idea of using mixing enhancement to reduce jet noise is not new. Lobed mixers have
been around since shortly after jet noise became a problem. However, these designs were …
