AbstractThree-dimensional oscillations of a liquid droplet are simulated numerically. The frequency and the damping for small amplitude are shown to agree well with the linear theory. Effects of initial amplitude and rotation on the oscillation frequency are studied, and it is found that the oscillation frequency decreases as the initial amplitude increases, while it increases as the rotation increases.
