摘要
采用黏性的CFD商业软件STAR-CCM+,基于重叠网格技术和DFBI(动态体驱动模块)模拟刚体的6-DOF运动,解决了滑行艇的动航态问题.通过建立波浪数值水池,对单M与双M船在迎浪规则波中的2-DOF运动进行数值模拟,对两者在迎浪规则波中的波浪增阻、运动响应和运动稳定性等问题进行比较分析.结果表明,双M船在迎浪规则波中更易发生跳跃现象,但是具有更小的增阻系数,同时在短波中具有更小的运动响应.
Based on the viscous CFD software STAR-CCM+,the 6-DOF motion of rigid body was simulated to solve the problem of the dynamic navigation state of planning craft by overset grid technology and DFBI(Dynamic Fluid-Body Interaction)module.Through the establishment of numerical wave tank,the 2-DOF motions of single M-hull and double M-hull ship(M&DM)in regular head waves were simulated separately.The comparison were analyzed on the wave added resistance,motion response and motion stability in regular head waves.The results show that it’s more likely to happen the jump phenomenon for DM in regular head waves but it has a lower added resistance coefficient.Meanwhile,the motion response of DM is smaller in short waves.
