It is generally said that pressure fluctuation induced by a body varying own volume with time is proportional to the second derivative of the volume. Pressure fluctuation induced by a cavitating wing is a good example. In this paper, we assume the modeled cavitation phenomenon that the thickness of the wing varies with time, and calculate pressure fluctuation above the wing which is represented by a simple surface panel method "SQCM". In calculation for a finite flat plate, we use three kinds of calculation methods: the first one uses a positive mirror image, the second one does the solid boundary factor 2.0, and the last one does QCM. Comparing these three kinds of results, we discuss the availability of the solid boundary factor and investigate the relation of the amplitude of pressure fluctuation and the second derivative of the wing volume.
