Abstract
In a two-phase flow exciting force evaluation method of the present invention, the surface of one of a plurality of tube bodies () is at least partially formed from a conductive material, displacement or stress of the tube body () is measured in a state of being vibrated by a shaking device (), and a void fraction of a two-phase flow (F) flowing in the vicinity of the tube body () is measured based on the potential difference between an electric potential at a predetermined position on the surface of the tube body (), and a reference electric potential.
