Structure of a submerged axisymmetric jet in its initial region

Abstract

On the basis of empirical results, a scheme is proposed for the development of a regular vortex structure in the mixing zone of the initial section of a submerged axisymmetric jet. A relation is established between different hydrodynamic characteristics in the jet.Recent studies [1-3 etc. ] have show~ that large-scale vortex structures characterized by a high degree of orderliness exist within the mixing zone of the initial section of a submerged axisymmetric Jet. As a result of the effect of these vortices, in the frequency spectra of turbulent energy i Eu(Odf = u '2 , 0
