摘要

A system of multipoint diagnostics for pressure pulsations was used in experiments. The data is compared with the results of high-speed flow visualization for the case of a cloud cavitation flow past a smooth hydrofoil in a slit channel. It was shown that the shock mechanism is significant for development of the attached cavity. The main mechanism for detachment and shedding of a cavity is a re-entrant flow.
