摘要
水下潜器在作业过程中因其表面遭受污损而影响水动力性能。针对泰勒水池公布的SUBOFF全附体模型,基于RANS方程研究粗糙度对水下潜器近海底在垂直面上斜航水动力性能的影响。对光滑SUBOFF模型在无限深广水域中的水动力开展数值研究,并用水池试验数据验证了计算结果的有效性。计算分析潜器的垂向力系数、纵倾力矩系数、压力分布和壁面剪切力等水动力特性,探究粗糙度、攻角和近海底距离对潜器水动力特性的影响,为深海作业潜器航行轨迹的控制与优化设计提供理论基础。
The hydrodynamic performance of an underwater submersible will be affected when it suffers from hard fouling in operation,Taking the SUBOFF full-attachment model published by David Taylor Model Basin as the research object,the influence of roughness on its oblique hydrodynamic performance on the vertical plane is studied using the RANS method.Numerical research is carried out for the smooth SUBOFF model in infinite depth,and the validity of the numerical calculation is verified by the test results.Hydrodynamic characteristics of the submersible,such as longitudinal force coefficient,vertical force coefficient,pitch moment coefficient,pressure distribution,and wall shear stress,are calculated and analyzed.Effects of roughness,angle of attack,and distance to the seabed on the hydrodynamic characteristics of the submersible are explored.The research will provide a theoretical basis for the control and optimization design of the navigation trajectory of deep-sea submersible operations.
