摘要 通过对微重力下球形容器内液体晃动的力学模型进行分析,将其模态函数用高斯超几何级数表示出来,然后对自由振动和受迫振动2种情形给出了速度势函数和液体表面位移函数关于所选择模态的数学表达式. In this papper, the modal analysis on the low-gravity slosh of a fluid in a Spherical tank is investigated. Firstly, the modal functions are denoted by Gauss hypergeometric series. Then the velocity potential and the liquid surface displacement are determined in terms of the modal functions for free slosh modal and forced slosh modal.
