| New results of experimental researches of a flow of the three-dimensional cavities executed as spherical segments of various diameter and depth are submitted. Experiments are carried out in the closed hydrodynamical tunnel by means of special adaptations. The technique consisting in preliminary visualization of flow structure and the further measurement by laser anemometer in found out characteristic places of fixed vortical structures is developed. Results of visualization are fixed by means of cameras and a video camera. New vortical structures in three-dimensional cavities and laws of their development are found out depending on speed of a flow and holes geometrical parameters. |
