ABSTRACT

A flow near the blind end in vortex chambers with angles of flow entry into the chamber of 0 and 45° relative to the tangential direction at different flow rates is investigated. The averaged values of the tangential and radial components of the velocity vector have been measured, as well as the values of their pulsations over the height of the end boundary layer with the aid of a two-component Doppler laser anemometer.
