Turbulent pressure fluctuations in acoustics and aerohydrodynamics

The turbulent pulsation of pressure is an important factor in the non -stationary effects of flows on streamlined structural elements and related generation of aerohydrodynamic noise. The book discusses a wide range of issues - from the general ideas about the spatio -temporal structure of the preferential turbulent pulsation of pressure to applied issues related to the effects of their impact on the formation of noise. Much attention is paid to the main methodological issues of measurements, the analysis of the characteristics and difficulties of measuring turbulent pulsation of pressure in the conditions of exposure to various random interference - from traditional acoustic and vibrational to thermal. More subtle issues related to the experimental all wavelength components of pressure pulsation and the determination of characteristic functionality are presented. The results of experimental studies on the study of the spatio-temporal structure of various heterogeneous fields of pressure pulsation and their modeling issues are presented in detail. A special place in the book is given to the issues of noise generation under the influence of pulsation of pressure and the effectiveness of various technical solutions related to the suppression of noise generated by the flow in various technical devices.
The book will be equally interesting to researchers developing measuring tools, experimental attitudes and methods of suppressing aerohydrodynamic noise, designers studying the features of aeroacoustic loading of aircraft, graduate students and senior students studying turbulent sources of noise
