摘要: 由力学平衡方程导出了旋转对称贮箱内静液面的二阶非线性常微分方程,接着具体推出了球腔、旋转椭球腔、柱面腔的边界接触角条件,最后使用Runge-Kutta法在计算机上得出了数值结果,绘出了静液面形状曲线,分析了算法特点。

关键词: 微重, 接触角, Bond数, 静液面形状

Abstract: By equilibrium equation of mechanics, the equation of static fluid surface in revolving symmtrical tank under low gravity has been derived. Boundary condition of contact angle is given. Finally, using Runge-Kutta method, numerical results are attained with the shape of static fluid surface drawn by the computer. Features of the computing method are analysed as well.

Key words: low gravity condition, contact angle, Bond number, shape of static liquid surface
