Excitation of velocity fluctuations and noise in a wind tunnel

The aim of this paper is to develop a theory, consistent with the observations, of the nature and location of the structures that determine self-excitation and the emission of the narrow-band components of the noise generated by the open working section of wind tunnels. At the same time, the theory is applied by using it as a basis for constructive solutions.Translated from Izvestiya Rossiiskoi Akademii Nauk, Mekhanika Zhidkosti i Gaza, No.4, pp. 165–173, July–August, 1992.
