Numerical simulation has become a practical tool for marine propeller designers. However, compared with experiments, the management and evaluation of the accuracy is generally more difficult. Especially when cavitation is involved, reliability of CFD is still much lower than that of experiments conducted in a cavitation tunnel. Uncertainty in CFD arises mainly from the approximation used in the mathematical model and discretization of the model. To clarify the sources of uncertainty and improve accuracy, it is necessary to carry out careful investigations through comparisons with reliable experimental data.
In this study, numerical simulations of non-cavitating and cavitating propellers in various conditions were performed and the results were compared with experimental data.
