摘要
以水下航行器上的腔体间距为研究对象,采用大涡数值模拟方法求解,建立了不同腔体间距的二维方腔模型,模拟其流场及声场特性,并分析流场与声场的相关性,揭示涡声关系,从而控制和改善水下航行器的涡流边界层流动状态,为其低阻力、低噪声及高可靠航行性能优化设计提供较好的理论工具。
Research the autonomous underwater vehicle as object. Use the multi-scale analysis method, and set up the water of the autonomous underwater vehicle dynamic model and numerical simulation method. Aiming at the multi-cavity of autonomous underwater vehicle, the influence of multi-cavity layout on the vortex field and the radiated noise field was investigated for the purpose of reducing the ship resistance and noise of, and provide necessary theoretical tools for its low resistance, low noise and high reliable navigation performance optimization design.
