Краткое описание

The role of wave disturbances in the viscous transonic flow formation, in the generation of stationary acoustic waves, and in the appearance of various self-oscillations of the separated flow is considered, including the case of the structural flow transformation at the critical regime. The influence of these disturbances on the growth of spectral density levels and on the correlation of pressure pulsations in both longitudinal and transverse directions is investigated at low frequencies. The data are obtained based on the experimental investigations of transonic flow over hammerhead cone-cylinder bodies.

Ключевые слова: acoustics, self-oscillations, separation
