Abstract

Cavitation is a prevalent phenomenon within the domain of ship and ocean engineering, predominantly occurring in the tail flow fields of high-speed rotating propellers and on the surfaces of high-speed underwater vehicles. The re-entrant jet and compression wave resulting from the collapse of cavity vapour are pivotal factors contributing to cavity instability. Concurrently, these phenomena significantly modulate the evolution of cavitation flow. In this paper, numerical investigations into cloud cavitation over a Clark-Y hydrofoil were conducted, utilizing the Large Eddy Simulation (LES) turbulence model and the Volume of Fluid (VOF) method within the OpenFOAM framework. Comparative analysis of results obtained at different angles of attack is undertaken. A discernible augmentation in cavity thickness is observed concomitant with the escalation in attack angle, alongside a progressive intensification in pressure at the leading edge of the hydrofoil, contributing to the suction force. These results can serve as a fundamental point of reference for gaining a deeper comprehension of cloud cavitation dynamics.
