基于CFD的并列超空泡射弹高速斜入水流体动力特性研究OA北大核心CSTPCD
CFD based study on the flow characteristics of parallel supercavitating projectiles entering water obliquely at high speed
在对水下目标连续、密集的打击过程中常常涉及到多体间的运动干扰和空泡非定常耦合等问题,使得流场结构和运动特性变得复杂.为分析并行超空泡射弹高速入水过程中流场的相互干扰规律,采用CFD方法建立并列弹高速斜入水流体动力特性研究数值模型,同时将并列弹与单个弹的计算结果进行对比,明确并列弹高速入水空泡形态和流场分布与单个弹的差异,并进一步给出弹间干扰特性随并列弹轴线间距的变化规律.计算结果表明:较单个弹入水过程,随着轴线间距的减小,并列弹的流体动力特性变化…查看全部>>
With the increasing demand of marine military,the realization of continuous and intensive strikes on underwater targets has gradually been paid attention to,and the process often involves problems such as motion interference between multiple bodies and non-constant coupling of cavities,which make the structure and motion characteristics become more complicated.A CFD method is adopted to establish the numerical model of high-speed oblique water entry hydrodyn…查看全部>>
