An experimental study has been carried out to investigate into a two-phase flow instability called the “geysering”. The regions are divided by the frequency and amplitude of pressure fluctuations caused by periodical bubble nucleations and its expansions. Experiments are conducted with a double tube closed thermosyphon which is made of glass to make visual observation possible. As the working fluid R113 is adopted. The mechanism of the geysering is described based on the visual observation of the phenomena as well as on the transients of temperature distributions of the outer tube.
