N2 - This work deals with the study of cavitation in a slit channel when flowing around NACA 0012 hydrofoils with a smooth and periodic-textured surface. The research was aimed at the description of the dynamics of cavitation development on smooth and rough hydrofoils and determination of differences between them. Computer modeling of cavitating flow in a slit channel formed behind an obstacle in the form of a hydrofoil was performed in the modern CFD package STAR-CCM+. Visualization was obtained, computer modeling was carried out in a wide range of parameters and a comparison with experimental data on the cavitating flow was made. The effect of periodic texture on the features of occurrence and development of a cavitation on the hydrofoil is described. The flow structure in cells of hydrofoil textured surface is shown. The obtained results can be used to control effectively the cavitation process in slit channels of various hydraulic engineering devices.
