Abstract基于RANS计算,开展长航程AUV螺旋桨的数值设计。该AUV设计航速仅2kn,要求阻力预报具有较高的精度;为此,各个方向的网格按相同尺度减小比率,设计了三套结构化网格,对阻力计算结果进行了数值不确定度分析。基于自航和敞水模拟,分析得到了实效伴流分布;应用升力线方法设计了适伴流最佳环量螺旋桨,采用螺旋桨进行了RANS自航模拟,预报了AUV的功率-转速-航速关系,并与湖试结果进行了初步比较,结果表明该方法具有良好的精度。
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.
