KeywordAuv 自航发射 三维混合网格 非结构动网格 水下对接
Abstract为研究AUV从有界流场自航发射到无界流场的运动边界的扰流场,文章采用了三维动态混合网格方法进行数值模拟的策略。混合网格由三菱柱/四面体/六面体网格构成,当AUV运动时,靠近AUV的三菱柱网格随AUV运动,外层是静止的六面体网格,中部的四面体网格随AUV运动而变形或者重构。数值仿真结果给出了不同时刻AUV表面的压力分布、整个航程AUV的阻力系数变化,其值与理论结果吻合。同时研究了直径比对发射管航行的附加质量和阻力系数的影响,这为水下对接AUV提供了有效手段。
Other AbstractA 3-D hybrid dynamic grids method is presented to simulate moving boundary in Autonomous Underwater Vehicle(AUV) swim-out from bounded domain to unbounded domain.The 3-D hybrid grids are composed of prismatic/tetrahedral/hexahedral grids from inner to outer layer respecitvely.With AUV moving the prismatic grids move with AUV,while the hexahedral grids remain stationary.Meanwhile,the tetrahedral grids are deformed or re-meshed according to the motion of AUV.Results from the numerical sim-ulation show that th...
