Boundary element simulation for behaviour of liquid drop
Abstract
This report discusses an application of boundary element analysis to the behavior of an oscillating 2-D (two-dimensional) liquid drop. The boundary element solution procedure used is based on the so-called mixed Eulerian-Lagrangian approach. The solution procedure is developed by using constant boundary elements and the Euler time integration scheme in conjunction with relocation and adaptation mesh techniques. In order to simulate the vibration of a liquid drop, an efficient procedure for the estimation of the local curvature on a free surface is introduced. Numerical results obtained in this study show the oscillating phenomena of the liquid drop subjected to a large amplitude of sinusoidal disturbance.
