Abstract
The system for PIV measurements in the flow with superimposed pulsations of the fluid (air) has been developed. Measurements of velocity and vorticity fields in a smooth duct in certain phases of superimposed pulsations have been performed. Statistics of a turbulent pulsating flow: velocity profiles, turbulent pulsations, and Reynolds stresses has been obtained.
