Abstract: [cze] [eng]
Bakalárska práca sa skladá z dvoch častí. Prvá časť sa venuje rešerši. Zaoberá sa objasnením základných pojmov kavitácie a súčasnému poznaniu v oblasti super- kavitácie. V druhej experimentálnej časti sa venuje procesom prúdenia Venturiho dýzou pri prechode z vyvinutej kavitácie do superkavitácie. Cieľom bolo preskúmať hysteréziu, ktorá nastáva zmenou smeru prechodu. Na objasnenie javu sa porovnali statické a dynamické charakteristiky získané z merania a vizualizácie na hydraulickom okruhu s kavitačnou tryskou. Bachelor thesis consists of two parts. The first part is dedicated to research. It deals with clarifying the basic concepts of cavitation and current knowledge in the field of supercavitation. The second, experimental part is devoted to flow in Venturi nozzle in the transition from developed cavitation to supercavitation. The aim was to examine the hysteresis that occurs with a change of transition direction. To clarify the phenomenon were compared static and dynamic characteristics acquired from the measurement and visualization on the hydraulic circuit with cavitation jet.
