| In the present work the problem in revealing a coherent vortical Goertler structures in a wall areas of a stream into the vortex chamber is put and solved. Scales of the vortical structures and their connection with a stream characteristics and scales of à introduced disturbances are determined. In experimental work a natural laws of formation of the longitudinal vortical systems under action of a mass forces which arise over a streamlined surface of the vortex chamber with longitudinal curvature are investigated. Specifical features of an occurrence of the Goertler vortices and their developments downwards on a stream over a streamline surface are shown. |
