摘要：
Data on the structure of a turbulent gas flow in a round tube under isothermal and nonisothermal conditions of flow were obtained experimentally. The data are used to calculate the frequency spectra of axial and radial velocity fluctuations. An analysis of the effect of nonisothermicity on the mechanisms underlying the incipience and development of turbulent pulsations is carried out.
