Turbulent jet modelling in a cross flow on the base of the vortex structure interaction

A mathematical model of a turbulen jet in a cross flow on the base of the vortex structure interaction, taking into consideration the jet cross-section deformation and non-self-simularity of its velocity cross profile, has been developel in the paper. Founding mechanisms of the jet mixing with a cross flow have been investigated. Rules of the turbulent jet propagation in a cross flow have been also investigated. The extremal character of the jet mixing with a cross flow has been established, the methodology of the jet main parametr calculation, which makes it possible to give prastical recommendations of the mixing process perfection in various technical devices, has been developedAvailable from VNTIC / VNTIC - Scientific & Technical Information Centre of RussiaSIGLERURussian Federatio
