AbstractThe behavior of liquid drop oscillation by using electrostatic-acoustic hybrid levitation equipment was observed. A relationship between amplitude and frequency shift was made clear and the experimental data concerning the effect of frequency shift on amplitude agreed well with numerical simulation and theory up to non-dimensional amplitude, epsilon, 0.3. But the effect of frequency shift on amplitude disagreed in larger than non-dimensional amplitude 0.3. The frequency shift became larger with increasing the amplitude of oscillation. In case of rotating drop, the frequency shift becomes smaller than that of irrotational case. The frequency shift agreed well with theory in the rotational case.
