Abstract Cavitation and cavitation erosion often occur and seriously threaten the safe and stable operation of hydraulic
machinery. However, during the operation of hydraulic machinery, the cavitation flow field is often difficult to
contact and measure, and the shedding and development characteristics of cavitation flow are unknown. This paper
uses the Detached Eddy Simulation (DES) turbulence model and Zwart-Gerber-Belamri (ZGB) cavitation model to
conduct numerical research on the cavitation flow of a twisted hydrofoil and verifies the effectiveness of numerical
simulation by comparing it with experimental results. Then, based on the fractal dimension method, the number
and fractal dimension of the… More >
