Abstract: The propeller noise is one of the three ship noise sources and very meaningful to study it. The structured grid of propeller is drawn firstly and mesh-convergence analysis is made. Then, LES is adopted to predict the propeller hydrodynamic performance. When predicting the radiation noise, three methods, such as FW-H equation, Virtual Lab rotating dipole radiation model and Powell vertex sound, are adopted. The computational results are in agreement well with experimental results. The results show that the LES combined with the three methods can predict propeller noise, and the three methods all satisfy the engineering application need.
