Abstracts:

The work reports the results of visualization of cavitation cavities and the experimental measurements of velocity of turbulent flow around a plane-parallel plate with rounded nose and a NACA0015 series foil by means of PIV approach. As a result, the spatial distributions of instantaneous flow velocity and vorticity were estimated. Afterwards, the spatial distributions of the mean flow velocity and turbulent kinetic energy were calculated. An analysis of spatial structure of the cavitation cavities was performed as well as a comparison of turbulent structure of the flows for cavitation and non-cavitation regimes.
