A new criteria to estimate an absolute unstable vibration of a tube array caused by liquid gas two-phase cross flow has been proposed here. This new criteria, which fits for the flow pattern from slug flow to froth flow, is based on the new method to calculate the flow speeds, the intermittantly rising velocity of the liquid slug, and that of the gas flow. The analytical results have been compared with the experimental data and the existense of the intermittant unstable vibration has been checked.
