Analysis of Liquid Drops Free Face Under the Effect of Gravity

摘要：

This article provides a method for obtaining the numerical solution about free face of static liquid drop under the effect of gravity. According to the Young-Laplace formula, buckling equation in differential calculus and geometrics, and the symmetry of free face of liquid, the control equation of static liquid drop under the effect of gravity is deduced. The boundary condition of volume is transferred to the radius condition of solid-liquid surface in order to use the Runge-Kutta method; through the coordinate system conversion, the Stiff problem is avoided; finally the calculated example is given.
