基于高精度的速度势boussinesq型方程,研究了二维矩形槽内的浅水晃动。考虑了矩形槽在小激励幅值条件下的谐波摆动、升沉和横摇运动。总速度势分为两部分:特解和由布西尼斯方程确定的剩余部分。横摇激振运动的特解采用Stokes-Joukowski势。数值结果的比较表明,基于boussinesq型方程可以很好地预测矩形槽内浅水晃动运动。
Based on the highly accurate Boussinesq-type equations in terms of velocity potential, the shallow-water sloshing in a two-dimensional rectangular tank is studied. The rectangular tank in harmonic sway, heave and roll motions with small excitation amplitudes is considered. The total velocity potential is divided into two parts: the particular solution and the remaining part to be determined by the Boussinesq-type equations. The Stokes-Joukowski potential is adopted in the particular solution for the roll excitation motion. The comparisons of the numerical results indicate that the shallow-water sloshing motions in a rectangular tank can be predicted well based on the Boussinesq-type equations.
