| Abstract: |
| Model experiment is an important method of hydrodynamic research. The ventilated cavitation experiment around revolution body always being extensive and complex, orthogonal design of ventilated cavitation experiment can reduce the amount of the cases，save expenditure and shorten the experiment cycle, obtain the main influence factors of the cavity characters based on the results analysis. This work was of a great engineering application value and effective guidance for following study in this field. |
