Structural Characteristics of the Cavern at a Fine Bubbled Stage of Cavitation

The article deals with shock pulses arising from the closure of bubbles, depending on the structure of the cavitation cavity. Since a fine-bubble stage of cavitation is usually observed on the elements of hydraulic structures, the structural characteristics of the three stages of the appearance of cavitation are further investigated. Studies of the structure of cavitation require the fixation of the spatial pattern of the bubble zone. This is due to the need to use a high intensity luminous flux with ultrashort exposure. To solve these problems, the holography method with the use of a ruby laser was applied
