Abstract
Photochromic visualization has been used to investigate the hydrodynamic flow which arises inside a sliding valve during its operation. The experimental setup and results of observations of the flows are described. Unsteady flows with different amplitudes and frequencies of the oscillations of the flow rate through the valve were investigated. The method makes is possible to determine the flow structure, construct profiles of the velocities and tangential stresses in the complete region within the valve, and also obtain data for calculating the hydrodynamic characteristics of valves.
