摘要
随着海洋探索的不断发展,水下作业对水下航行器提出了更高的要求。为了提高某水下航行器的减阻性能,本文基于计算流体力学(computational fluid dynamics,CFD)方法对预选的多种艏部型线以及舵板进行数值模拟,对比了它们的减阻性能,最终为航行器选择效果最佳的艏部型线以及舵板,并计算配备有最佳减阻效果的艇艏和舵板的航行器总阻力,对比分析其周围压力和流场特性。结果显示,所选的零部件相较于其他选择拥有更好的减阻性能,更适用于本文的水下航行器。本文研究结果可为航行器的结构设计和选择提供一定的参考。
With the continuous development of ocean exploration,underwater operations put forward higher requirements for underwater vehicles.In order to improve the resistance reduction performance of an underwater vehicle,based on the computational fluid dynamics(CFD)method,this paper carries out numerical simulation for a variety of pre-selected bow profiles and rudder plates,compares their resistance reduction performances,finally selects the best bow profile and rudder plate for the vehicle.In addition,the total resistance of the vehicle equipped with the bow and rudder plates with the optimum resistance reduction effect is calculated,the surrounding pressure and flow-field characteristics are compared and analyzed.The results show that,the selected components have better resistance reduction performance than other options and are more suitable for the underwater vehicle proposed in this paper.The results of this research can provide a certain reference for the structural design and selection of underwater vehicles.
