Abstract: Oscillations and rotations of a liquid droplet are simulated numerically using the level set method, and the combined effects of oscillation amplitude and rotation rate on the drop-shape oscillation is studied. The oscillation frequency is shown to decrease as the amplitude of oscillation increases. The oscillation frequency increases, in contrast to the effect of amplitude, as the rotation rate increases. The pressure distribution in the droplet corresponds to the frequency shift, and it is shown that the oscillations without frequency shift are possible. It is found that the relation between the amplitude and the rotation rate is linear both for the frequency shift of zero and for the pressure difference of zero even though the fluid properties are different. The flow fields in and around the droplet are visualized, and it is shown that the vortices formed by the oscillation are not affected by the rotation. Parallel computations are performed with satisfactory h!
igh efficiency for the calculations of the pressure field, and the importance of the communication rate is demonstrated.
