| Abstract | This paper presents a practical calculation method for pressure fluctuation induced by cavitating propeller. The method is based on a simple surface panel method “SQCM” and treats the three types of cavitation, sheet cavitation, tip super cavitation and tip vortex cavitation. The calculation method based on a potential flow theory is generally expected to be light calculation load for the initial stage of propeller design. However, it is difficult to satisfy the need because it must be able to calculate not only cavity area but also cavity volume in order to predict the pressure fluctuation theoretically. The present method in this paper improves the authors' previous method (Kanemaru et al 2015) for the practicability with maintaining the accuracy as much as possible. The main feature in this method is that the cavitation calculation is conducted about key blade only, in other words, about one blade propeller. The interaction between blades is considered using the data of inflow velocity components from other blades to the key blade, which is calculated without cavitation in advance. The calculated cavitation pattern, cavity volume and pressure fluctuation are shown comparing with the experimental data. |
