Abstract

The cavitation flow images are always used to research cavitation phenomena. A cavitation flow image program is developed, which introduces many self-designing image processing functions different from the general ones and overcome the restrictions of the commercial softwares. By employing the program, the outline, boundary, gray level and area of the flow images around a super-cavitation hydrofoil in the cavitation zone can be extracted successfully. Moreover, the evolutional period of cavitation can be estimated based on image gray, so that the cavity configuration and transformation can be researched quantificationally. The reliability and frequency of the processing cavitation have been improved in order to understand the mechanism of cavitation flow.
