Other AbstractBased on RANS simulation, a numerical methodology of propeller design is developed for low-speed and long-range AUVs. As design speed of the AUV under consideration is only 2 knots, high accuracy of resistance prediction is required. Numerical uncertainty in resistance simulation is analyzed based on three sets of structured grids having a unified refinement ratio of the grid. Effective wake profile is predicted via self-propulsion and open-water simulation, where the propeller is simulated with a body-force model. An optimal propeller in non-uniform effective wake is designed by means of the lifting-line theory. The delivered power and rotational speed of the propeller are predicted via unsteady RANS simulation of self-propulsion. A comparison of the RANS-prediction with the trial test indicates that the present numerical methodology is effective and reasonably accurate for design of the propeller on the low-speed AUV and prediction of the powering performance.
