Sound Scattering Caused by the Temperature Inhomogeneities in a Wake Behind the Cylinder

ABSTRAKT

The sound wave scattering caused by temperature discontinuities in a vortex street is researched. The wake-flow structure was induced for a weak-heated and for a heat-insulated cylinder surveyed. The task is solved in Born approximation and in a ray approximation. The expressions linking characteristics of a scattering sound wave with thermodynamic and kinematic flow parameters are obtained.
