摘要
利用商用CFD软件STAR-CCM+12.06对航行器线形与推进性能的关系及其阻力特性进行数值仿真研究,针对搭载拖曳线列阵声呐的小口径航行器进行流体动力仿真,详细分析了影响航行器航行品质的因素和有效减阻的方法,为优化结构布局提供初步的理论参考依据,仿真与试验结果符合较好。
In this paper,the relation of vehicle profile and thrust characteristic and the drag characteristic are numerically simulated by a commercial CFD software STAR-CCM+12.06,and future perform hydrodynamic simulation against small-bore vehicle carrying towed line array sonar.The factors effecting quality of navigation and the way to reduce drag are analyzed in detail.Which offers preliminary theoretical foundation to optimize structure.The experimental and numerical simulation results are fit quite well.
