摘要
本文分析并计算了部分充液球形贮箱内的液体晃动问题。以流体运动的基本方程和系统的Euler动力学方程为基础,考虑了贮箱偏置、流体涡旋以及Coriolis加速度诸因素对于系统运动状态的影响;并运用Pfeiffer推广的关于流体均匀涡旋运动的概念和边界元法等计算了流固耦合旋转系统运动状态的变化规律。
In the paper, the liquid sloshing in a partially liquid-filled spherical tank is investigated. The basic equations of fluid and the Euler dynamic equations construct the governing equations of the system. Considering the influence on the liquid motion and the state of the system of off-centre tanks, vorticity of 1iquid and coriolis acceleration, and using the concept of homogeneous vorticity introduced by Pfeiffer and the boundary element method, the state variance of the fluid-solid coupled system is calculated.
