Abstract
The paper deals with a comparison between experimental data obtained b y Blanc-Benon (1984) and theoretical predictions of the coherence func tion of a spherical sound wave after passing through a turbulent jet. The predictions are based on the theory of sound propagation in moving random media recently developed by Ostashev (1994, 1997), which corre ctly takes into account the effects of an isotropic vector random fiel d of the medium velocity fluctuations on Line-of-sight sound propagati on. It is shown that the theoretical predictions fit the data well. (C ) Academic des Sciences/Elsevier, Paris.
