4228 液滴の振動周波数に及ぼす振幅と回転の影響(G05-13 気泡・液滴(2),G05 流体工学)  [in Japanese] 4228 Effect of Amplitude and Rotation on Oscillation Frequency of a Droplet  [in Japanese]

Three-dimensional oscillations and rotations of a liquid droplet are simulated numerically using the level set method. It is found that the oscillation frequency decreases as the initial amplitude increases, while it increases as the rotation frequency increases. It is found that the oscillation frequency depends on the average pressure difference between the pole and the equator of the droplet.
