Investigation of High Speed Cavitation Flows
- 1 Faculty of Mechanical Engineering, STU Bratislava, Slovakia
The paper presents an investigation of cavitating flow behind a micro-orifice. Experiments were performed with a device making visualization of a cavitation cloud possible. Two micro-orifices of the sizes 0.58 mm and 0.35 mm were tested at different cavitation numbers and at different flow rates. Parameters of the cavitation cloud collapse on a smooth surface were found. The experimental device, experiment methodology and some results are presented. Results of visualization are compared with CFD simulations.
