【摘要】 研究水下运动体绕流场的离散化方法,运动体周遭流场的分布情况是研究基于运动体绕流场探测原理的基础。本文建立了研究流场特征与运动体运动参数相关性的分析方法,实现了运动体在无障碍水域中航行时的信息还原,建立了绕流场离散化分析的流网分析方法。结果表明,运动体周遭流场分布特征明显,其周遭压力场、速度场、头部物理参量的分布以及流场流线分布具有较强的规律性,综合运动体表面物理参量的分布特征,并结合流网中几何参量与物理参量的衍化规律,可以实现对整个运动体绕流场的离散化描述。更多还原

【Abstract】 The study of the dispersion method of the underwater motion around the flow field and the distribution of the flow field around the moving body are the basis for studying the principle of motion around the flow field. The method of analyzing the correlation between the flow field and the motion parameters of the moving body is established to realize the information reduction of the moving body in the barrierless waters. The results show that the distribution of the flow field around the body is obvious, and the distribution of the pressure field, the velocity field, the distribution of the physical parameters of the head and the flow field distribution of the flow field are strong. The flow net And the distribution of physical parameters on the surface of the moving body can be realized by combining the geometrical parameters and the physical parameters in the flow net.更多还原
