This paper describes the results of experiments conducted to determine the damping and hydrodynamic mass characteristics of a fixed-fixed cylinder both in liquid and in simulated two-phase flows. It was observed that damping was significantly higher in two-phase flow than in single phase flow, and that, depending on the flow regime, it exhibited a maximum or maxima at void fractions of 30% to 60% . The hydrodynamic mass was observed to decrease with increasing void fraction but at a higher rate than that of the mixture density.
