| New results of experimental researches of flow of two hemispherical segment deepening's of various diameter and depth, having the rounded off edges are presented. Experiments are lead in the closed hydrodynamic pipe by means of special adaptations. Profiles longitudinal time-averaged and pulsating speeds are measured by means of laser anemometer on various distances in vicinity and above cavities. New physical features of flow of vortical structures in three-dimensional deepening are found out. Three characteristic conditions of flow of vortical structures in cavities depending on Reynolds's numbers are classified. |
