Numerical method for predicting ship propeller cavitation noise

During ship travels in high-velocity, propeller cavitation noise predominates in the radiated noise sources. However, experiential data regress method was use to predicate propeller cavitation noise in the past. In this article, propeller cavitation noise has been calculated by numerical computation method. From the engineering point of view, ship propeller has been disposed as a dipole bubble. Bubble volume pulse of propeller-blade has been computed by surface panel method. Propeller cavitation noise has been gained by using Lighthill equation to transform propeller bubble volume pulse. The cavitation noise of one ship propeller model has been calculated using this method.
