A re-examination is made of the two-dimensional interaction of a plane, time-harmonic
sound wave with a rectilinear vortex of small core diameter at low Mach number. Sakov [1] …

The well-known two-dimensional problem of sound scattering by a Rankine vortex at small
Mach number M is considered. Despite its long history, the solutions obtained by many …

The instability of the compressible Rankine vortex is investigated using a multioperators-
based scheme with the tenth-order approximation to the convection terms of the fluid …

Problem of noise generation by localized vortices is investigated. At the begining of the
paper the theory of sound radiation by vortex ring is discussed briefly. This theory based on …

The scattering of acoustic waves by compact three-dimensional axisymmetric vortices is
studied using direct numerical simulation in the case where the incoming wave is aligned …

Проведено численное моделирование классической задачи о малых колебаниях вихря
Ранкина в сжимаемом газе. Уравнения Эйлера для сжимаемого газа решались …

The well-known two-dimensional problem of a plane acoustic wave scattering by a point
vortex is ill-posed because the vortex velocity field decays as, the solution matches the …

Проведено исследование процесса формирования и динамики элементарного объекта
газовой динамики вихревого кольца. Рассматривались интенсивные турбулентные …

A review of recent achievements in the investigation of mechanisms of aerodynamic sound
generation by turbulent vortices is presented. The results obtained, and their agreement …
