Sinopsis

The main emphasis of the work is put on experimental study of spatial structure and dynamics of gas-vapor cavities and turbulent structure of cavitating turbulent flows around the plate with rounded nose, the NACA0015 hydrofoil and the cascade of three identical NACA0015 hydrofoils. The flows were investigated for different angles of incidence α = 0, 3, 6 and 9° with variation of cavitation number σ from 6 for the cascade down to 0.6 for the single hydrofoil. As a result, the full set of statistical moments of turbulent fluctuations (including the third-order ones) was calculated for all the regimes. Comparison of turbulent characteristics was performed for different cavity types and the main particularities of the flows were pointed out.
